Looking at #3762 it seemed to have been caused by calling
`setCurrentPage` during a `select.editing_shape` interaction. I wonder
whether we should trigger a `cancel` event before switching pages in
case this happens?

This revives the old 'derived camera' idea to prevent cursor wobbling
during viewport following.
Before this PR we updated the camera on a tick during viewport
following, but the shapes and cursors were not moving on the same tick
(we tried that during the perf work and it was all kinds of
problematic). Frankly I've forgotten how we ever managed to eliminate
wobble here in the first place?
Anyway after this PR we derive the camera based on whether or not we are
following a user. When you follow a user it makes it so that your
viewport contains their viewport. If your viewport is not already very
close to their viewport it will animate the initial position, after
which it will 'lock' in place and the derived value will be used from
then on.
This exposed a minor issue in our sync engine: the fact that we send
presence updates in separate websocket messages from document updates.
We get into situations like this
1. user A follows user B
2. user B deletes the current page they are on
3. user B's page deletion diff gets sent
4. user B's presence update gets sent with a new currentPageId
5. user A receives the page deletion
6. user A still thinks that user B is on the old page and doesn't know
how to update the follow state.
So to fix this I made it so that we can (and do) send presence updates
in the same websocket messages as document updates so the server can
handle them atomically.

Focus management is really scattered across the codebase. There's sort
of a battle between different code paths to make the focus the correct
desired state. It seemed to grow like a knot and once I started pulling
on one thread to see if it was still needed you could see underneath
that it was accounting for another thing underneath that perhaps wasn't
needed.
The impetus for this PR came but especially during the text label
rework, now that it's much more easy to jump around from textfield to
textfield. It became apparent that we were playing whack-a-mole trying
to preserve the right focus conditions (especially on iOS, ugh).
This tries to remove as many hacks as possible, and bring together in
place the focus logic (and in the darkness, bind them).
## Places affected
- [x] `useEditableText`: was able to remove a bunch of the focus logic
here. In addition, it doesn't look like we need to save the selection
range anymore.
- lingering footgun that needed to be fixed anyway: if there are two
labels in the same shape, because we were just checking `editingShapeId
=== id`, the two text labels would have just fought each other for
control
- [x] `useFocusEvents`: nixed and refactored — we listen to the store in
`FocusManager` and then take care of autoFocus there
- [x] `useSafariFocusOutFix`: nixed. not necessary anymore because we're
not trying to refocus when blurring in `useEditableText`. original PR
for reference: https://github.com/tldraw/brivate/pull/79
- [x] `defaultSideEffects`: moved logic to `FocusManager`
- [x] `PointingShape` focus for `startTranslating`, decided to leave
this alone actually.
- [x] `TldrawUIButton`: it doesn't look like this focus bug fix is
needed anymore, original PR for reference:
https://github.com/tldraw/tldraw/pull/2630
- [x] `useDocumentEvents`: left alone its manual focus after the Escape
key is hit
- [x] `FrameHeading`: double focus/select doesn't seem necessary anymore
- [x] `useCanvasEvents`: `onPointerDown` focus logic never happened b/c
in `Editor.ts` we `clearedMenus` on pointer down
- [x] `onTouchStart`: looks like `document.body.click()` is not
necessary anymore
## Future Changes
- [ ] a11y: work on having an accessebility focus ring
- [ ] Page visibility API:
(https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API)
events when tab is back in focus vs. background, different kind of focus
- [ ] Reexamine places we manually dispatch `pointer_down` events to see
if they're necessary.
- [ ] Minor: get rid of `useContainer` maybe? Is it really necessary to
have this hook? you can just do `useEditor` → `editor.getContainer()`,
feels superfluous.
## Methodology
Looked for places where we do:
- `body.click()`
- places we do `container.focus()`
- places we do `container.blur()`
- places we do `editor.updateInstanceState({ isFocused })`
- places we do `autofocus`
- searched for `document.activeElement`

### Release Notes
- Focus: rework and untangle existing focus management logic in the SDK
Before this PR the interface for doing cleanup when shapes/bindings were
deleted was quite footgunny and inexpressive.
We were abusing the shape beforeDelete callbacks to implement
copy+paste, which doesn't work in situations where cascading deletes are
required. This caused bugs in both our pin and sticker examples, where
copy+paste was broken. I noticed the same bug in my experiment with text
labels, and I think the fact that it took us a while to notice these
bugs indicates other users are gonna fall prey to the same bugs unless
we help them out.
One suggestion to fix this was to add `onAfterDelete(From|To)Shape`
callbacks. The cascading deletes could happen in those, while keeping
the 'commit changes' kinds of updates in the `before` callbacks and
theoretically that would fix the issues with copy+paste. However,
expecting people to figure this out on their own is asking a heckuva lot
IMO, and it's a heavy bit of nuance to try to convey in the docs. It's
hard enough to convey it here. Plus I could imagine for some users it
might easily even leave the store in an inconsistent state to allow a
bound shape to exist for any length of time after the shape it was bound
to was already deleted.
It also just makes an already large and muddy API surface area even
larger and muddier and if that can be avoided let's avoid it.
This PR clears things up by making it so that there's only one callback
for when a binding is removed. The callback is given a `reason` for why
it is being called
The `reason` is one of the following:
- The 'from' is being deleted
- The 'to' shape is being deleted
- The binding is being deleted on it's own.
Technically a binding might end up being deleted when both the `from`
and `to` shapes are being deleted, but it's very hard to know for
certain when that is happening, so I decided to just ignore it for now.
I think it would only matter for perf reasons, to avoid doing useless
work.
So this PR replaces the `onBeforeDelete`, `onAfterDelete`,
`onBeforeFromShapeDelete` and `onBeforeToShapeDelete` (and the
prospective `onAfterFromShapeDelete` and `onAfterToShapeDelete`) with
just two callbacks:
- `onBeforeUnbind({binding, reason})` - called before any shapes or the
binding have been deleted.
- `onAfterUnbind({binding, reason})` - called after the binding and any
shapes have been deleted.
This still allows all the same behaviour as before, without having to
spread the logic between multiple callbacks. It's also just clearer IMO
since you only get one callback invocation per unbinding rather than
potentially two. It also fixes our copy+paste footgun since we can now
implement that by just deleting the bindings rather than invoking the
`onBeforeDelete(From|To)Shape` callbacks.
I'm not worried about losing the explicit before/after delete callbacks
for the binding record or shape records because sdk users still have the
ability to detect all those situations with full nuance in obvious ways.
The one thing that would even require extra bookkeeping is getting
access to a shape record after the shape was deleted, but that's
probably not a thing anybody would want to do 🤷🏼

in many places, we use a pattern like `React.createContext({} as
Editor)` when defining contexts. This causes a problem: `{}` is not
`Editor`, but you can still `useEditor` wherever you like and your code
with run with this confusing non-editor value.
This diff updates all our `createContext` calls to default to `null`,
with an explicit check and error for missing values. Now, if you
`useEditor` outside of `<Tldraw />`, you'll get a message telling you
that it can only be used within `<Tldraw />`.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features
### Release Notes
`useEditor` and other context-based hooks will now throw an error when
used out-of-context, instead of returning a fake value.
This adds a store-level "operation end" event which fires at the end of
atomic operations. It includes some other changes too:
- The `SideEffectManager` now lives in & is a property of the store as
`StoreSideEffects`. One benefit to this is that instead of overriding
methods on the store to register side effects (meaning the store can
only ever be used in one place) the store now calls directly into the
side effect manager, which is responsible for dealing with any other
callbacks
- The history manager's "batch complete" event is gone, in favour of
this new event. We were using the batch complete event for only one
thing, calling `onChildrenChange` - which meant it wasn't getting called
for undo/redo events, which aren't part of a batch. `onChildrenChange`
is now called after each atomic store operation affecting children.
I've also added a rough pin example which shows (kinda messily) how you
might use the operation complete handler to traverse a graph of bindings
and resolve constraints between them.

With the new work on bindings, we no longer need to keep any arrows
stuff hard-coded in `editor`, so let's move it to `tldraw` with the rest
of the shapes.
Couple other changes as part of this:
- We had two different types of `WeakMap` backed cache, but we now only
have one
- There's a new free-standing version of `createComputedCache` that
doesn't need access to the editor/store in order to create the cache.
instead, it returns a `{get(editor, id)}` object and instantiates the
cache on a per-editor basis for each call.
- Fixed a bug in `createSelectedComputedCache` where the selector
derivation would get re-created on every call to `get`

### Release Notes
#### Breaking changes
- `editor.getArrowInfo(shape)` has been replaced with
`getArrowInfo(editor, shape)`
- `editor.getArrowsBoundTo(shape)` has been removed. Instead, use
`editor.getBindingsToShape(shape, 'arrow')` and follow the `fromId` of
each binding to the corresponding arrow shape
- These types have moved from `@tldraw/editor` to `tldraw`:
- `TLArcInfo`
- `TLArrowInfo`
- `TLArrowPoint`
- `WeakMapCache` has been removed
First draft of the new bindings API. We'll follow this up with some API
refinements, tests, documentation, and examples.
Bindings are a new record type for establishing relationships between
two shapes so they can update at the same time.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `feature` — New feature
### Release Notes
#### Breaking changes
- The `start` and `end` properties on `TLArrowShape` no longer have
`type: point | binding`. Instead, they're always a point, which may be
out of date if a binding exists. To check for & retrieve arrow bindings,
use `getArrowBindings(editor, shape)` instead.
- `getArrowTerminalsInArrowSpace` must be passed a `TLArrowBindings` as
a third argument: `getArrowTerminalsInArrowSpace(editor, shape,
getArrowBindings(editor, shape))`
- The following types have been renamed:
- `ShapeProps` -> `RecordProps`
- `ShapePropsType` -> `RecordPropsType`
- `TLShapePropsMigrations` -> `TLPropsMigrations`
- `SchemaShapeInfo` -> `SchemaPropsInfo`

This PR adds a slideshow example (similar to @TodePond's slides but more
on rails) as a way to put some pressure on camera controls.
Along the way, it fixes some issues I found with animations and the new
camera controls.
- forced changes will continue to force through animations
- animations no longer set unnecessary additional listeners
- animations end correctly
- updating camera options does not immediately update the camera (to
allow for animations, etc.)
It also changes the location of the "in front of the canvas" element so
that it is not hidden by the hit test blocking element.
### Change Type
- [x] `sdk` — Changes the tldraw SDK

This PR implements a camera options API.
- [x] Initial PR
- [x] Updated unit tests
- [x] Feedback / review
- [x] New unit tests
- [x] Update use-case examples
- [x] Ship?
## Public API
A user can provide camera options to the `Tldraw` component via the
`cameraOptions` prop. The prop is also available on the `TldrawEditor`
component and the constructor parameters of the `Editor` class.
```tsx
export default function CameraOptionsExample() {
return (
<div className="tldraw__editor">
<Tldraw cameraOptions={CAMERA_OPTIONS} />
</div>
)
}
```
At runtime, a user can:
- get the current camera options with `Editor.getCameraOptions`
- update the camera options with `Editor.setCameraOptions`
Setting the camera options automatically applies them to the current
camera.
```ts
editor.setCameraOptions({...editor.getCameraOptions(), isLocked: true })
```
A user can get the "camera fit zoom" via `editor.getCameraFitZoom()`.
# Interface
The camera options themselves can look a few different ways depending on
the `type` provided.
```tsx
export type TLCameraOptions = {
/** Whether the camera is locked. */
isLocked: boolean
/** The speed of a scroll wheel / trackpad pan. Default is 1. */
panSpeed: number

This prevents duplicating shapes if we get to the max allowed shapes.
Before this change we would create as many shapes as we could and skip
the rest. After this change we don't create any shapes in this case.
We already do this for [copy
pasting](https://github.com/tldraw/tldraw/blob/mitja%2Fduplicate-shapes/packages/editor/src/lib/editor/Editor.ts#L7595-L7600)
(via `putContentOntoCurrentPage`), so no change was needed there.

### Release Notes
- fixes an edge case in multiplayer rooms where the room can crash if an
arrow's bound shape is deleted by a peer
This PR fixes a bug where alt-dragging the left or right handles of a
text shape would not produce the correct outcome: the width would double
but the center would change.
This is because the text shape is aspect ratio locked only when dragging
handles other than the left or right, but we didn't have the ability to
differentiate between that. We've had to add that optionality in,
together with a hard-coded override of the normal behavior for text
shapes.

When a device has both a touch screen and a mouse, pointer: coarse
evaluates to false and then doesn't change even if the user begins to
use the touch screen.
In this PR pointer: coarse is replaced with any-pointer: coarse, which
checks if a touchscreen input is available. Event listeners for
touchstart and mousemove update isCoursePointer dynamically. So if the
user begins to move the mouse it changes to pointer: fine, if they then
touch the screen the pointer is returned to coarse.

Our undo-redo system before this diff is based on commands. A command
is:
- A function that produces some data required to perform and undo a
change
- A function that actually performs the change, based on the data
- Another function that undoes the change, based on the data
- Optionally, a function to _redo_ the change, although in practice we
never use this
Each command that gets run is added to the undo/redo stack unless it
says it shouldn't be.
This diff replaces this system of commands with a new one where all
changes to the store are automatically recorded in the undo/redo stack.
You can imagine the new history manager like a tape recorder - it
automatically records everything that happens to the store in a special
diff, unless you "pause" the recording and ask it not to. Undo and redo
rewind/fast-forward the tape to certain marks.
As the command concept is gone, the things that were commands are now
just functions that manipulate the store.
One other change here is that the store's after-phase callbacks (and the
after-phase side-effects as a result) are now batched up and called at
the end of certain key operations. For example, `applyDiff` would
previously call all the `afterCreate` callbacks before making any
removals from the diff. Now, it (and anything else that uses
`store.atomic(fn)` will defer firing any after callbacks until the end
of an operation. before callbacks are still called part-way through
operations.
## Design options
Automatic recording is a fairly large big semantic change, particularly
to the standalone `store.put`/`store.remove` etc. commands. We could
instead make not-recording the default, and make recording opt-in
instead. However, I think auto-record-by-default is the right choice for
a few reasons:
1. Switching to a recording-based vs command-based undo-redo model is
fundamentally a big semantic change. In the past, `store.put` etc. were
always ignored. Now, regardless of whether we choose record-by-default
or ignore-by-default, the behaviour of `store.put` is _context_
dependant.
2. Switching to ignore-by-default means that either our commands don't
record undo/redo history any more (unless wrapped in
`editor.history.record`, a far larger semantic change) or they have to
always-record/all accept a history options bag. If we choose
always-record, we can't use commands within `history.ignore` as they'll
start recording again. If we choose the history options bag, we have to
accept those options in 10s of methods - basically the entire `Editor`
api surface.
Overall, given that some breaking semantic change here is unavoidable, I
think that record-by-default hits the right balance of tradeoffs. I
think it's a better API going forward, whilst also not being too
disruptive as the APIs it affects are very "deep" ones that we don't
typically encourage people to use.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features
- [x] `galaxy brain` — Architectural changes
### Release Note
#### Breaking changes
##### 1. History Options
Previously, some (not all!) commands accepted a history options object
with `squashing`, `ephemeral`, and `preserveRedoStack` flags. Squashing
enabled/disabled a memory optimisation (storing individual commands vs
squashing them together). Ephemeral stopped a command from affecting the
undo/redo stack at all. Preserve redo stack stopped commands from wiping
the redo stack. These flags were never available consistently - some
commands had them and others didn't.
In this version, most of these flags have been removed. `squashing` is
gone entirely (everything squashes & does so much faster than before).
There were a couple of commands that had a special default - for
example, `updateInstanceState` used to default to being `ephemeral`.
Those maintain the defaults, but the options look a little different now
- `{ephemeral: true}` is now `{history: 'ignore'}` and
`{preserveRedoStack: true}` is now `{history:
'record-preserveRedoStack'}`.
If you were previously using these options in places where they've now
been removed, you can use wrap them with `editor.history.ignore(fn)` or
`editor.history.batch(fn, {history: 'record-preserveRedoStack'})`. For
example,
```ts
editor.nudgeShapes(..., { ephemeral: true })
```
can now be written as
```ts
editor.history.ignore(() => {
editor.nudgeShapes(...)
})
```
##### 2. Automatic recording
Previously, only commands (e.g. `editor.updateShapes` and things that
use it) were added to the undo/redo stack. Everything else (e.g.
`editor.store.put`) wasn't. Now, _everything_ that touches the store is
recorded in the undo/redo stack (unless it's part of
`mergeRemoteChanges`). You can use `editor.history.ignore(fn)` as above
if you want to make other changes to the store that aren't recorded -
this is short for `editor.history.batch(fn, {history: 'ignore'})`
When upgrading to this version of tldraw, you shouldn't need to change
anything unless you're using `store.put`, `store.remove`, or
`store.applyDiff` outside of `store.mergeRemoteChanges`. If you are, you
can preserve the functionality of those not being recorded by wrapping
them either in `mergeRemoteChanges` (if they're multiplayer-related) or
`history.ignore` as appropriate.
##### 3. Side effects
Before this diff, any changes in side-effects weren't captured by the
undo-redo stack. This was actually the motivation for this change in the
first place! But it's a pretty big change, and if you're using side
effects we recommend you double-check how they interact with undo/redo
before/after this change. To get the old behaviour back, wrap your side
effects in `editor.history.ignore`.
##### 4. Mark options
Previously, `editor.mark(id)` accepted two additional boolean
parameters: `onUndo` and `onRedo`. If these were set to false, then when
undoing or redoing we'd skip over that mark and keep going until we
found one with those values set to true. We've removed those options -
if you're using them, let us know and we'll figure out an alternative!
These were needed when the docs lived in a different repo, but they
don't any more so we can get rid of them.

Fixes culling for cases when another user would drag shapes inside your
viewport. We weren't correctly calculating the culling status for arrows
that might be bound to those shapes and also for shapes within dragged
in groups / frames.

(this is a PR redo of https://github.com/tldraw/tldraw/pull/3424 which
got messed up a bit)
It doesn't quite feel like this is the right fix but it does solve the
issue. I was trying to see if `getShapeAtPoint` needed more work but the
further I went in that rabbit hole it seemed like I shouldn't touch that
code without causing a bunch of disruption at the moment.
Specifically, the code that does `Check labels first` in Editor.ts is a
little obscure (lines 4384-4397). It only checks a couple specifics
shapes (with certain combinations, i.e. a geo with "none" fill) _and_ it
doesn't check `hitLabels` which also maybe feels wrong? I tried
unraveling it but there's a lot of code relying on it at the moment to
mess with it in the stickies work.

https://github.com/tldraw/tldraw/pull/1806 for historical context fwiw)

Something was bothering me a bit with the discussion around sqrt's being
slow. Looks like `Math.hypot` has a performance cost associated with it.
Looking at the Chromium source code:
https://chromium.googlesource.com/v8/v8/+/4.3.21/src/math.js?autodive=0%2F%2F#19
and
https://source.chromium.org/chromium/chromium/src/+/main:v8/src/builtins/math.tq;l=36?q=math&sq=&ss=chromium%2Fchromium%2Fsrc:v8%2Fsrc%2F
it looks like maybe we'd be avoiding the multiple arguments that can be
passed into Math.hypot which is maybe the source of the perf hit.
Also, interestingly in `math.tq` you can see it doing this funky sqrt
calculation: `Float64Sqrt((a / max) * (a / max) + (b / max) * (b / max))
* max` - I think that possibly is trying to avoid some overflow in some
cases with bigger numbers, but also possibly with a perf hit.
[edit]: OK, actually on Firefox, doing sqrt seems slower - but digging
more into this, it looks like doing `** 0.5` instead of `sqrt` is much
faster.

Adds RBush to handle spatial querying. We use it for:
- Culling. Helps a lot with panning as we don't have to compute the
culled shapes from scratch. Instead we just query rbush again. It makes
culling quite granular: spatial index updates when shapes change
(additions, removals, changes to bounds), visible shapes depends on
that, but also updates when the viewport page bound change, culled
shapes then depend on that but also change with selections changes. The
api stayed the same, which is great since the fuzz tests can stay as
they are.
- Brushing
- Erasing
- Scribble brushing
- Getting shapes at point (for example, when updating the hover id)
This improves performance of all of those operations. I might have
missed some places where this might also be useful.

### Release Notes
#### BREAKING CHANGES
- The `Migrations` type is now called `LegacyMigrations`.
- The serialized schema format (e.g. returned by
`StoreSchema.serialize()` and `Store.getSnapshot()`) has changed. You
don't need to do anything about it unless you were reading data directly
from the schema for some reason. In which case it'd be best to avoid
that in the future! We have no plans to change the schema format again
(this time was traumatic enough) but you never know.
- `compareRecordVersions` and the `RecordVersion` type have both
disappeared. There is no replacement. These were public by mistake
anyway, so hopefully nobody had been using it.
- `compareSchemas` is a bit less useful now. Our migrations system has
become a little fuzzy to allow for simpler UX when adding/removing
custom extensions and 3rd party dependencies, and as a result we can no
longer compare serialized schemas in any rigorous manner. You can rely
on this function to return `0` if the schemas are the same. Otherwise it
will return `-1` if the schema on the right _seems_ to be newer than the
schema on the left, but it cannot guarantee that in situations where
migration sequences have been removed over time (e.g. if you remove one
of the builtin tldraw shapes).
Generally speaking, the best way to check schema compatibility now is to
call `store.schema.getMigrationsSince(persistedSchema)`. This will throw
an error if there is no upgrade path from the `persistedSchema` to the
current version.
- `defineMigrations` has been deprecated and will be removed in a future
release. For upgrade instructions see
https://tldraw.dev/docs/persistence#Updating-legacy-shape-migrations-defineMigrations
- `migrate` has been removed. Nobody should have been using this but if
you were you'll need to find an alternative. For migrating tldraw data,
you should stick to using `schema.migrateStoreSnapshot` and, if you are
building a nuanced sync engine that supports some amount of backwards
compatibility, also feel free to use `schema.migratePersistedRecord`.
- the `Migration` type has changed. If you need the old one for some
reason it has been renamed to `LegacyMigration`. It will be removed in a
future release.
- the `Migrations` type has been renamed to `LegacyMigrations` and will
be removed in a future release.
- the `SerializedSchema` type has been augmented. If you need the old
version specifically you can use `SerializedSchemaV1`

There was a bug that could occur if you pinched while using the hand
tool, where on pinch end the hand tool would slide the camera based on
the pinching velocity. The fix is to cancel out any velocity while
pinching.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `bugfix` — Bug fix
### Test Plan
On mobile...
1. Select the hand tool.
2. Begin a pinch
3. Stop the pinch
4. The camera should stay where it is
### Release Notes
- Fixed a bug that could occur while pinching with the hand tool
selected.
This PR adds a computed cache for masked shape page bounds, which speeds
up visibility checks (a lot!).

Before we were running this on any change, even mouse position changes.
Now we only run it when shapes change.
Results wouldn't change in any case, so there's not a huge improvement.
Still, why run it if it is not necessary.

This PR makes a small improvement to the way we measure distances.
(Often we measure distances multiple times per frame per shape on the
screen). In many cases, we compare a minimum distance. This makes those
checks faster by avoiding a square root.

We also need to clear the timeout when panning.

Had an [alternative
approach](https://github.com/tldraw/tldraw/pull/3444) of setting
timeouts and clearing them in dispatch, but since the timeout is 500ms I
think this should work as well.

Next.js bans the use of react-dom/server APIs on the client. React's
docs recommend against using these too:
https://react.dev/reference/react-dom/server/renderToString#removing-rendertostring-from-the-client-code
In this diff, we switch from using `ReactDOMServer.renderToStaticMarkup`
to `ReactDOMClient.createRoot`, fixing SVG exports in next.js apps.
`getSvg` remains deprecated, but we've introduced a new `getSvgElement`
method with a similar API to `getSvgString` - it returns an `{svg,
width, height}` object.

Reworks our culling logic:
- No longer show the gray rectangles for culled shapes.
- Don't use `renderingBoundExpanded`, instead we now use
`viewportPageBounds`. I've removed `renderingBoundsExpanded`, but we
might want to deprecate it?
- There's now a incremental computation of non visible shapes, which are
shapes outside of `viewportPageBounds` and shapes that outside of their
parents' clipping bounds.
- There's also a new `getCulledShapes` function in `Editor`, which uses
the non visible shapes computation as a part of the culled shape
computation.
- Also moved some of the `getRenderingShapes` tests to newly created
`getCullingShapes` tests.
Feels much better on my old, 2017 ipad (first tab is this PR, second is

We use text shadows to create "outlines" around text shapes. These
shadows are rendered on the GPU. In Chrome (and on computers with a
capable GPU) text shadows work pretty well, however on Safari—and in
particular on iOS—they cause massive frame drops.

This PR adds a "long press" event that fires when pointing for more than
500ms. This event is used in the same way that dragging is used (e.g. to
transition to from pointing_selection to translating) but only on
desktop. On mobile, long presses are used to open the context menu.
## Background
This idea came out of @TodePond's #3208 PR. We use a "dead zone" to
avoid accidentally moving / rotating things when clicking on them, which
is especially common on mobile if a dead zone feature isn't implemented.
However, this makes it difficult to make "fine adjustments" because you
need to drag out of the dead zone (to start translating) and then drag
back to where you want to go.
With this change, you can long press on desktop to get to that
translating state. It's a micro UX optimization but especially nice if
apps want to display different UI for "dragging" shapes before the user
leaves the dead zone.

### Release Notes

This PR fixes a bug that was introduced by #3223. There was a code path
that normally used to never run (a blur event running when the shape was
no longer editing) but which was being run now that shapes aren't

This PR buffs input events.
## The story so far
In the olde days, we throttled events from the canvas events hook so
that a pointer event would only be sent every 1/60th of a second. This
was fine but made drawing on the iPad / 120FPS displays a little sad.
Then we removed this throttle. It seemed fine! Drawing at 120FPS was
great. We improved some rendering speeds and tightened some loops so
that the engine could keep up with 2x the number of points in a line.
Then we started noticing that iPads and other screens could start
choking on events as it received new inputs and tried to process and
render inputs while still recovering from a previous dropped frame. Even
worse, on iPad the work of rendering at 120FPS was causing the browser
to throttle the app after some sustained drawing. Yikes!
### Batching
I did an experimental PR (#3180) to bring back batching but do it in the
editor instead. What we would do is: rather than immediately processing
an event when we get it, we would instead put the event into a buffer.
On the next 60FPS tick, we would flush the buffer and process all of the
events. We'd have them all in the same transaction so that the app would
only render once.
### Render batching?
We then tried batching the renders, so that the app would only ever
render once per (next) frame. This added a bunch of complexity around
events that needed to happen synchronously, such as writing text in a
text field. Some inputs could "lag" in a way familiar to anyone who's
tried to update an input's state asynchronously. So we backed out of
this.
### Coalescing?
Another idea from @ds300 was to "coalesce" the events. This would be
useful because, while some interactions like drawing would require the
in-between frames in order to avoid data loss, most interactions (like
resizing) didn't actually need the in-between frames, they could just
use the last input of a given type.
Coalescing turned out to be trickier than we thought, though. Often a
state node required information from elsewhere in the app when
processing an event (such as camera position or page point, which is
derived from the camera position), and so the coalesced events would
need to also include this information or else the handlers wouldn't work
the way they should when processing the "final" event during a tick.
So we backed out of the coalescing strategy for now. Here's the [PR that
removes](937469d69d)
it.
### Let's just buffer the fuckers
So this PR now should only include input buffering.
I think there are ways to achieve the same coalescing-like results
through the state nodes, which could gather information during the
`onPointerMove` handler and then actually make changes during the
`onTick` handler, so that the changes are only done as many time as
necessary. This should help with e.g. resizing lots of shapes at once.
But first let's land the buffering!
---
Mitja's original text:
This PR builds on top of Steve's [experiment
PR](https://github.com/tldraw/tldraw/pull/3180) here. It also adds event
coalescing for [`pointerMove`
events](https://github.com/tldraw/tldraw/blob/mitja/input-buffering/packages/editor/src/lib/editor/Editor.ts#L8364-L8368).
The API is [somewhat similar
](https://developer.mozilla.org/en-US/docs/Web/API/PointerEvent/getCoalescedEvents)
to `getCoalescedEvent`. In `StateNodes` we register an `onPointerMove`
handler. When the event happens it gets called with the event `info`.
There's now an additional field on `TLMovePointerEvent` called
`coalescedInfo` which includes all the events. It's then on the user to
process all of these.
I decided on this API since it allows us to only expose one event
handler, but it still gives the users access to all events if they need
them.
We would otherwise either need to:
- Expose two events (coalesced and non-coalesced one and complicate the
api) so that state nodes like Resizing would not be triggered for each
pointer move.
- Offer some methods on the editor that would allow use to get the
coalesced information. Then the nodes that need that info could request
it. I [tried
this](9ad973da3a (diff-32f1de9a5a9ec72aa49a8d18a237fbfff301610f4689a4af6b37f47af435aafcR67)),
but it didn't feel good.
This also complicated the editor inputs. The events need to store
information about the event (like the mouse position when the event
happened for `onPointerMove`). But we cannot immediately update inputs
when the event happens. To make this work for `pointerMove` events I've
added `pagePoint`. It's
[calculated](https://github.com/tldraw/tldraw/pull/3223/files#diff-980beb0aa0ee9aa6d1cd386cef3dc05a500c030638ffb58d45fd11b79126103fR71)
when the event triggers and then consumers can get it straight from the
event (like
[Drawing](https://github.com/tldraw/tldraw/pull/3223/files#diff-32f1de9a5a9ec72aa49a8d18a237fbfff301610f4689a4af6b37f47af435aafcR104)).

This PR tweaks the logic of _when_ we update the viewport screen bounds.
Previously, we updated every one second in order to capture any changes
to the viewport's screen position. In this PR, we _check_ every one
second and update the screen bounds if the viewport's screen position
has actually changed. Since we also update the rendering shapes when
this happens, it would cause the rendering / culling shapes to update
while the camera was moving.
I've also removed the "maximum time before we start culling shapes", as
this wasn't very useful and could also cause frames to start dropping
without recovering.

### Change Type
- [x] `minor` — New feature
### Release Notes
- Refactor textfields be composable/swappable.
Adds reference docs, guide in the "Editor" article, and examples for the
side effects manager.
There are 4 new examples:
1. Before create/update shape - constrains shapes to be places within a
circle
2. Before delete shape - prevent red shapes from being deleted
3. After create/update shape - make sure there's only ever one red shape
on the page at a time
4. After delete shape - delete frames after their last child is deleted
As these examples all require fairly specific configurations of shapes
(or are hard to understand without some visual hinting in the case of
placing shapes within a circle), I've included a `createDemoShapes`
function in each of these which makes sure the examples start with
shapes that will quickly show you the side effects in action. I've kept
these separate from the main code (in a function at the bottom), so
hopefully that won't be a source of confusion to anyone working from
these examples.

## Migration path
1. If any of your shapes implement `toSvg` for exports, you'll need to
replace your implementation with a new version that returns JSX (it's a
react component) instead of manually constructing SVG DOM nodes
2. `editor.getSvg` is deprecated. It still works, but will be going away
in a future release. If you still need SVGs as DOM elements rather than
strings, use `new DOMParser().parseFromString(svgString,
'image/svg+xml').firstElementChild`
## The change in detail
At the moment, our SVG exports very carefully try to recreate the
visuals of our shapes by manually constructing SVG DOM nodes. On its own
this is really painful, but it also results in a lot of duplicated logic
between the `component` and `getSvg` methods of shape utils.
In #3020, we looked at using string concatenation & DOMParser to make
this a bit less painful. This works, but requires specifying namespaces
everywhere, is still pretty painful (no syntax highlighting or
formatting), and still results in all that duplicated logic.
I briefly experimented with creating my own version of the javascript
language that let you embed XML like syntax directly. I was going to
call it EXTREME JAVASCRIPT or XJS for short, but then I noticed that we
already wrote the whole of tldraw in this thing called react and a (imo
much worse named) version of the javascript xml thing already existed.
Given the entire library already depends on react, what would it look
like if we just used react directly for these exports? Turns out things
get a lot simpler! Take a look at lmk what you think
This diff was intended as a proof of concept, but is actually pretty
close to being landable. The main thing is that here, I've deliberately
leant into this being a big breaking change to see just how much code we
could delete (turns out: lots). We could if we wanted to make this
without making it a breaking change at all, but it would add back a lot
of complexity on our side and run a fair bit slower

This diff mostly adds an image annotator example, but also has a couple
of drive-by changes:
- Added a 'use-cases' category to the examples app for this style of
mini-app
- Add `editor.pageToViewport`, which is like `editor.pageToScreen` but
works with viewport coordinates (better for `InFrontOfTheCanvas` stuff)
- Prevent the chrome side-swipe-to-go-back thing in the examples app
Some cool features of the image annotator:
- The image cannot be unlocked, and cannot have shapes places behind it
- I still need to work out a way of removing the context menu though
- Anything you place outside the bounds of the image (and therefore
outside the bounds of the export) will be greyed out
- You can't change pages
- unless you find the "move to page" action... need to fix that
- The camera is constrained! It'll keep the image roughly centered on
the screen. If you pick a very long thin image, you can only scroll
vertically. If you pick a very big one, it'll default it to a reasonable
size.

The probelm was manifesting because our camera updates were not
throttled and our render tick was on a different tick timeline to our
tick manager. Fixing the latter gets rid of the lag without requiring us
to throttle the camera updates.

This PR fixes an issue where events happening on tick were not batched.
We were listening to the `tick` event directly from the state node,
rather than passing the event into the state chart at the top. This
meant that it was bypassing the regular state chart rules, which was
what got me looking at this; but then I noticed that we also weren't
batching the changes, either. This causes computed stuff to re-compute
after each atom is updated within the `onTick` handler, which can be a
LOT.

It's not game breaking but it's important enough to hotfix at least in
the dot com.

### Test Plan
1. Select many shapes.
2. Resize them.
### Release Notes
- Fix a performance issue effecting resizing multiple shapes.
This PR is a minor cleanup of the Shape component.
Here we:
- use some dumb memoized info to avoid unnecessary style changes
- move the dpr check up out of the shapes themselves, avoiding renders
on instance state changes
Culled shapes:
- move the props setting on the culled shape component to a layout
reactor
- no longer set the height / width on the culled shape component
- no longer update the culled shape component when the shape changes
Random:
- move the arrow shape defs to the arrow shape util (using that neat API
we didn't used to have)

### Test Plan
1. Use shapes
2. Use culled shapes
### Release Notes
- SDK: minor improvements to the Shape component
This PR makes a few tiny improvements to the way that selection page
bounds and rotated page bounds are calculated.
For bounds, we bail once we find a different rotation among the selected
shapes. Previously, we grabbed all of the rotations first before
comparing them; we only need to grab rotations until we find a rotation
that's different from the first one.
For rotating page bounds, we only look at the corners of the calculated
bounds, and we mutate the resulting points after we transform them.
Previously, we looked at all vertices and make a copy of the points when
rotating them. The transform already creates the copy, so we can mutate
it; and while the bounds are usually calculated from the vertices, using
the corners gives us fewer points to transform.

whether or not that shape had handles.

Apparently we were supposed to do this for the previous release, and the
release notes mentioned the document title, so I'm doing a quick hotfix
for dotcom.

When we went from overrides-based to component based UI customisation
APIs, we didn't do the toolbar because it had some significant extra
complexity around overflowing the contents of the menu into the
dropdown. This is really hard to do at render-time with react - you
can't introspect what a component will return to move some of it into an
overflow.
Instead, this diff runs that logic in a `useLayoutEffect` - we render
all the items into both the main toolbar and the overflow menu, then in
the effect (or if the rendered components change) we use CSS to remove
the items we don't need, check which was last active, etc. Originally, I
wasn't really into this approach - but i've actually found it to work
super well and be very reliable.

Adds tests for the Vec.Average. [My previous
PR](https://github.com/tldraw/tldraw/pull/3065) added a check that
prevented returning vectors with NaNs, this adds a test for that.

Should fix `At instance.duplicateProps.offset.x: Expected a number, got
NaN` validation errors.
Wasn't able to reproduce. We only assign the offset here, so
`Vec.Averge` is the most likely offender here and for that to happen I
guess `movingShapes` might not contain any shapes.

Steve tried this in #3043, but we reverted it in #3063. Steve's version
added `JSON.parse`/`JSON.stringify` to the helpers without checking for
where we were already `JSON.parse`ing (or not). In some places we just
store strings directly rather than wanting them jsonified, so in this
version we leave the jsonification to the callers - the helpers just do
the reading/writing and return the string values.
### Change Type
- [x] `patch` — Bug fix
We use `children: any` in a bunch of places, but the proper type for
these is `ReactNode`. This diff fixes those.
