editor: register timeouts/intervals/rafs for disposal (#3852)
We have a lot of events that fire in the editor and, technically, they
can fire after the Editor is long gone.
This adds a registry/manager to track those timeout/interval/raf IDs
(and some eslint rules to enforce it).

Some other cleanups:
- `requestAnimationFrame.polyfill.ts` looks like it's unused now (it
used to be used in a prev. revision)
- @ds300 I could use your feedback on the `EffectScheduler` tweak. in
`useReactor` we do: `() => new EffectScheduler(name, reactFn, {
scheduleEffect: (cb) => requestAnimationFrame(cb) }),`
and that looks like it doesn't currently get disposed of properly.
thoughts? happy to do that separately from this PR if you think that's a
trickier thing.

Snapshots pit of success (#3811)
Lots of people are having a bad time with loading/restoring snapshots
and there's a few reasons for that:

- It's not clear how to preserve UI state independently of document
state.
- Loading a snapshot wipes the instance state, which means we almost
always need to
  - update the viewport page bounds
  - refocus the editor
  - preserver some other sneaky properties of the `instance` record

Add select option to Editor.groupShapes and Editor.ungroupShapes (#3690)
This PR adds an (optional) options argument to the `Editor.groupShapes`
and `Editor.ungroupShapes` methods.

Taha's original PR:

This PR seeks to make it easier to disentangle shape selection logic
from the grouping shapes logic. This is one of two approaches we could
take to this problem.

Other PR is here: https://github.com/tldraw/tldraw/pull/3691

I think this is a better method because it doesn't require consumers of
the library with their own custom actions to change the way their own
grouping logic works. As evidenced by all the tests failing on the other
PR.

Move constants to options prop (#3799)
Another go at #3628 & #3783. This moves (most) constants into
`editor.options`, configurable by the `options` prop on the tldraw
component.

### Change Type

- [x] `feature` — New feature

### Release Notes

You can now override many options which were previously hard-coded
constants. Pass an `options` prop into the tldraw component to change
the maximum number of pages, grid steps, or other previously hard-coded
values. See `TldrawOptions` for more

rework canBind callback (#3797)
This PR reworks the `canBind` callback to work with customizable
bindings. It now accepts an object with a the shape, the other shape
(optional - it may not exist yet), the direction, and the type of the
binding. Devs can use this to create shapes that only participate in
certain binding types, can have bindings from but not to them, etc.

If you're implementing a binding, you can see if binding two shapes is
allowed using `editor.canBindShapes(fromShape, toShape, 'my binding
type')`

### Change Type

- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features

### Release Notes

#### Breaking changes
The `canBind` flag now accepts an options object instead of just the
shape in question. If you're relying on its arguments, you need to
change from `canBind(shape) {}` to `canBind({shape}) {}`.

Force interface instead of type for better docs (#3815)
Typescript's type aliases (`type X = thing`) can refer to basically
anything, which makes it hard to write an automatic document formatter
for them. Interfaces on the other hand are only object, so they play
much nicer with docs. Currently, object-flavoured type aliases don't
really get expanded at all on our docs site, which means we have a bunch
of docs content that's not shown on the site.

This diff introduces a lint rule that forces `interface X {foo: bar}`s
instead of `type X = {foo: bar}` where possible, as it results in a much
better documentation experience:

focus: rework and untangle existing focus management logic in the sdk (#3718)
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`

[bindings] beforeUnbind/afterUnbind to replace beforeDelete/afterDelete (#3761)
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 🤷🏼

No defaults for contexts (#3750)
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 />`.

- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features

Store-level "operation end" event (#3748)
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.

Move arrow helpers from editor to tldraw (#3721)
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`

### Change Type

- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features

### 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

Bindings (#3326)
First draft of the new bindings API. We'll follow this up with some API

### Change Type

#### 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`

Camera options followups (#3701)
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.

		<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

	panSpeed: number

Fix text resizing with alt key (#3632)
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.

![Kapture 2024-04-28 at 13 48
52](https://github.com/tldraw/tldraw/assets/23072548/ad339a57-4efd-4201-86bc-c03a379f7e0c)

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.

Automatic undo/redo (#3364)
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!

RBush again? (#3439)
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.

### Erasing before (Test on my old ipad)

### 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`

Fix SVG exports in Next.js (#3446)
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.

Perf: Incremental culled shapes calculation. (#3411)
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
current prod, third is staging).

Perf: (slightly) faster min dist checks (#3401)
This PR improves a bunch of places where we do "minimum distance
checks". Previously, we were using `Vec.Dist`, which uses `Math.hypot`
to find the actual distance, but we can just as well use the squared
distance. So this PR makes a small improvement to `Vec.Dist2` and then

Display none for culled shapes (#3291)
Comparing different culling optimizations:


https://github.com/tldraw/tldraw/assets/2523721/0b3b8b42-ed70-45b7-bf83-41023c36a563

I think we should go with the `display: none` + showing the skeleteon.
The way it works is:
- We now add a sibling to the shape wrapper div which serves as the
skeleton for the culled shapes.
- Only one of the two divs (shape wrapper and skeleton div) is
displayed. The other one is using `display: none` to improve
performance.

Add long press event (#3275)
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.

![Kapture 2024-03-26 at 18 57

## 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.

![Kapture 2024-03-26 at 19 00

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.

side effects reference docs & examples (#3258)
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.

React-powered SVG exports (#3117)
## 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

Add image annotator example (#3147)
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.

[fix] Batch tick events (#3181)
This PR fixes an issue where events happening on tick were not batched. 

![Kapture 2024-03-17 at 22 49
52](https://github.com/tldraw/tldraw/assets/23072548/2bcfa335-a38f-46c4-a3f3-434cac61b6ce)

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.

Component-based toolbar customisation API (#3067)
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.

[feature] wrap mode (#2938)
By default, tldraw's brushing mode will select when the box intersects
an shape's geometry. A user can hold Command / Ctrl to require that the
selection box fully contain a shape's bounds instead.

Some people really prefer the opposite. Three years! Three years I've
been saying "no no no".

This PR adds a user preference to flip the logic. When `isWrapMode` is
true, selection requires that the box completely contain a shape before
it's added to the list of selecting shapes; and ctrl flips back to
intersection instead.

### Change Type

- [x] `minor` — New feature

### Test Plan

1. Turn on wrap mode in the user preferences menu.
2. Select stuff.
3. Use the ctrl key to except the behavior back to intersection.

- [x] Unit Tests

### Release Notes

- Added `isWrapMode` to user preferences.
- Added Wrap Mode toggle to user preferences menu.

Faster validations + record reference stability at the same time (#2848)
This PR adds a validation mode whereby previous known-to-be-valid values
can be used to speed up the validation process itself. At the same time
it enables us to do fine-grained equality checking on records much more
quickly than by using something like lodash isEqual, and using that we
can prevent triggering effects for record updates that don't actually
alter any values in the store.

Here's some preliminary perf testing of average time spent in
`store.put()` during some common interactions

| task | before (ms) | after (ms) |
| ---- | ---- | ---- |
| drawing lines | 0.0403 | 0.0214 |
| drawing boxes | 0.0408 | 0.0348 |
| translating lines | 0.0352 | 0.0042 |
| translating boxes | 0.0051 | 0.0032 |
| rotating lines | 0.0312 | 0.0065 |
| rotating boxes | 0.0053 | 0.0035 |
| brush selecting boxes | 0.0200 | 0.0232 |
| traversal with shapes | 0.0130 | 0.0108 |
| traversal without shapes | 0.0201 | 0.0173 |

**traversal** means moving the camera and pointer around the canvas

#### Discussion

At the scale of hundredths of a millisecond these .put operations are so
fast that even if they became literally instantaneous the change would
not be human perceptible. That said, there is an overall marked
improvement here. Especially for dealing with draw shapes.

These figures are also mostly in line with expectations, aside from a
couple of things:

- I don't understand why the `brush selecting boxes` task got slower
after the change.
- I don't understand why the `traversal` tasks are slower than the
`translating boxes` task, both before and after. I would expect that
.putting shape records would be much slower than .putting pointer/camera
records (since the latter have fewer and simpler properties)

[Snapping 6/6] Self-snapping API (#2869)
This diff adds a self-snapping API for handles. Self-snapping is used
when a shape's handles want to snap to the shape itself. By default,
this isn't allowed because moving the handle might move the snap point,
which creates a janky user experience.

Now, shapes can return customised versions of their normal handle
snapping geometry in these cases. As a bonus, line shapes now snap to
other handles on their own line!
