This PR fixes a bug where the indicator on a locked group (or any
shape!) would not appear when the shape was unlocked. This happens
because the `memo` equality checker filtered out changes to the shape's
locked property if they did not effect any other properties.

### Change Type
- [x] `patch` — Bug fix
### Release Notes
- Fix case where indicator was not shown when unlocking groups
This PR makes it so that locked shapes do not show an indicator when
hovered.

### Test Plan
1. Hover a locked shape
2. Hover a shape, then lock it
### Release Notes
- locked shapes do not show an indicator when hovered
This PR is a significant rewrite of our selection / hit testing logic.
It
- replaces our current geometric helpers (`getBounds`, `getOutline`,
`hitTestPoint`, and `hitTestLineSegment`) with a new geometry API
- moves our hit testing entirely to JS using geometry
- improves selection logic, especially around editing shapes, groups and
frames
- fixes many minor selection bugs (e.g. shapes behind frames)
- removes hit-testing DOM elements from ShapeFill etc.
- adds many new tests around selection
- adds new tests around selection
- makes several superficial changes to surface editor APIs
This PR is hard to evaluate. The `selection-omnibus` test suite is
intended to describe all of the selection behavior, however all existing
tests are also either here preserved and passing or (in a few cases
around editing shapes) are modified to reflect the new behavior.
## Geometry
All `ShapeUtils` implement `getGeometry`, which returns a single
geometry primitive (`Geometry2d`). For example:
```ts
class BoxyShapeUtil {
getGeometry(shape: BoxyShape) {
return new Rectangle2d({
width: shape.props.width,
height: shape.props.height,
isFilled: true,
margin: shape.props.strokeWidth
})
}
}
```
This geometric primitive is used for all bounds calculation, hit
testing, intersection with arrows, etc.
There are several geometric primitives that extend `Geometry2d`:
- `Arc2d`
- `Circle2d`
- `CubicBezier2d`
- `CubicSpline2d`
- `Edge2d`
- `Ellipse2d`
- `Group2d`
- `Polygon2d`
- `Rectangle2d`
- `Stadium2d`
For shapes that have more complicated geometric representations, such as
an arrow with a label, the `Group2d` can accept other primitives as its
children.
## Hit testing
Previously, we did all hit testing via events set on shapes and other
elements. In this PR, I've replaced those hit tests with our own
calculation for hit tests in JavaScript. This removed the need for many
DOM elements, such as hit test area borders and fills which only existed
to trigger pointer events.
## Selection
We now support selecting "hollow" shapes by clicking inside of them.
This involves a lot of new logic but it should work intuitively. See
`Editor.getShapeAtPoint` for the (thoroughly commented) implementation.

every sunset is actually the sun hiding in fear and respect of tldraw's
quality of interactions
This PR also fixes several bugs with scribble selection, in particular
around the shift key modifier.

...as well as issues with labels and editing.
There are **over 100 new tests** for selection covering groups, frames,
brushing, scribbling, hovering, and editing. I'll add a few more before
I feel comfortable merging this PR.
## Arrow binding
Using the same "hollow shape" logic as selection, arrow binding is
significantly improved.

a thousand wise men could not improve on this
## Moving focus between editing shapes
Previously, this was handled in the `editing_shapes` state. This is
moved to `useEditableText`, and should generally be considered an
advanced implementation detail on a shape-by-shape basis. This addresses
a bug that I'd never noticed before, but which can be reproduced by
selecting an shape—but not focusing its input—while editing a different
shape. Previously, the new shape became the editing shape but its input
did not focus.

In this PR, you can select a shape by clicking on its edge or body, or
select its input to transfer editing / focus.

tldraw, glorious tldraw

- [editor] Add `Editor.getShapeGeometry`
This PR removes several extraneous computed values from the editor. It
adds some silly instance state onto the instance state record and
unifies a few methods which were inconsistent. This is fit and finish
work 🧽
## Computed Values
In general, where once we had a getter and setter for `isBlahMode`,
which really masked either an `_isBlahMode` atom on the editor or
`instanceState.isBlahMode`, these are merged into `instanceState`; they
can be accessed / updated via `editor.instanceState` /
`editor.updateInstanceState`.
## tldraw select tool specific things
This PR also removes some tldraw specific state checks and creates new
component overrides to allow us to include them in tldraw/tldraw.

This PR adds a `meta` property to shapes and other records.
It adds it to:
- asset
- camera
- document
- instance
- instancePageState
- instancePresence
- page
- pointer
- rootShape
## Setting meta
This data can generally be added wherever you would normally update the
corresponding record.
An exception exists for shapes, which can be updated using a partial of
the `meta` in the same way that we update shapes with a partial of
`props`.
```ts
this.updateShapes([{
id: myShape.id,
type: "geo",
meta: {
nemesis: "steve",
special: true
}
])
```
## `Editor.getInitialMetaForShape`
The `Editor.getInitialMetaForShape` method is kind of a hack to set the
initial meta property for newly created shapes. You can set it
externally. Escape hatch!

This PR fixes a few components that were updating too often. It changes

as changed props.

This diff adds a new property to `defineShape`: `tool`.
The tool prop allows shapes to bring a tool along with them as part of
their definition. E.g. the draw shape isn't much use without the draw
tool, so adding the draw shape to your app gives you the draw tool tool.
As part of this, i renamed the `shapeutils` folder to just `shapes`, and
moved a bunch of shape-specific tools from the tools folder into the
shapes folder. This more closely reflects how things will be once we
move our default shapes out of core for tldraw-zero.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
Tested locally
### Release Notes
n/a
Turns out there was one last terrible renaming PR to make. This PR
renames the `@tldraw.editor`'s `app` folder to `editor`. It should not
effect exports but it will be a gnarly diff.
### Change Type
- [x] `internal` — Any other changes that don't affect the published
package (will not publish a new version)
This PR renames all exported types to include the `TL` prefix. It also
removes the `TL` prefix from things that are not types, including:
- shape utils (e.g. `TLArrowUtil` becomes `ArrowShapeUtil`)
- tools (e.g. `TLArrowTool` becomes `ArrowShapeTool`, `TLSelectTool`
becomes `SelectTool`)
### Change Type
- [x] `major` — Breaking Change
### Release Notes
- Renaming of types, shape utils, tools
This PR renames `App`, `app` and all appy names to `Editor`, `editor`,
and editorry names.
### Change Type
- [x] `major` — Breaking Change
### Release Notes
- Rename `App` to `Editor` and many other things that reference `app` to
`editor`.
This PR fixes several issues with the way that SVG overlays were
rendered.
- fixes editing embed shape on firefox (weird SVG pointer events bug)
- fixes layering of overlays
- collaborator cursors are offset
### Change Type
- [x] `patch` — change to unshipped changes
### Test Plan
1. Try editing an embed shape on Firefox
2. Confirm that cursor hints are no longer spinning
3. Confirm that cursors are displayed correctly over other shapes
This PR has been hijacked! 🗑️🦝🦝🦝
The <Canvas> component was previously split into an <SVGLayer> and an
<HTMLLayer>, mainly due to the complexity around translating SVGs.
However, this was done before we learned that SVGs can have overflow:
visible, so it turns out that we don't really need the SVGLayer at all.
This PR now refactors away SVG Layer.
It also updates the class name prefix in editor from `rs-` to `tl-` and
does a few other small changes.
