There are a lot of cases (eg when interacting with the ui) where the
editor loses focus. This check was preventing us from updating the
viewport screen bounds when appropriate. This function is throttled and
pretty cheap anyway (if the viewport is equal its a no-op) so let's just
remove the condition

This PR restores the controlled nature of focus. Focus allows keyboard
shortcuts and other interactions to occur. The editor's focus should
always / entirely be controlled via the autoFocus prop or by manually
setting `editor.instanceState.isFocused`.
Design note: I'm starting to think that focus is the wrong abstraction,
and that we should instead use a kind of "disabled" state for editors
that the user isn't interacting with directly. In a page where multiple
editors exit (e.g. a notion page), a developer could switch from
disabled to enabled using a first interaction.

This PR fixes an issue where images would overflow the shape's true
height or width.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Create an image shape.
2. Resize the image shape and look at the edges.
We got things sliggghhhtly wrong in #1980. That diff was attempting to
fix a bug where the text measurement element would refuse to go above
the viewport size in safari. This was most obvious in the case where
there was no fixed width on a text shape, and that diff fixed that case,
but it was also happening when a fixed width text shape was wider than
viewport - which wasn't covered by that fix. It turned out that that fix
also introduced a bug where shapes would no longer grow along the y-axis
- in part because the relationship between `width`, `maxWidth`, and
`minWidth` is very confusing.
The one-liner fix is to just use `max-content` instead of `fit-content`
- that way, the div ignores the size of its container. But I also
cleared up the API for text measurement to remove the `width` property
entirely in favour of `maxWidth`. I think this makes things much clearer
and as far as I can tell doesn't affect anything.
Closes#1998
### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Create an arrow & geo shape with labels, plus a note and text shape
2. Try to break text measurement - overflow the bounds, make very wide
text, experiment with fixed/auto-size text, etc.
Fixes an issue with creating arrows. Currently we create an arrow that
has both `start` and `end` handles set to the same point. This causes
`NaN` issues in some of our functions / svg rendering. After this change
we only create the arrow after we start dragging, which ensures the
start and the end handle won't have the same coordinates. This probably
feels the best way to approach it: arrow of length 0 doesn't really make
sense.

Fixes#1996
This fixes a few issues with cloud rendering:
- At small sizes the arcs could get kind of inverted after being
mutated, so you'd end calculating the outline using the large arc
instead of the small arc and it would balloon the size of the bounds
(that was what Mitja was seeing in #1996
- While working on the above I noticed that there are some situations
where we were actually supposed to be using the large arc for rendering
the svg paths but we were using the small arcs instead, making the
bounds appear larger than the cloud shape when in fact the cloud shape
was too small.
- I also fixed some other issues related to rendering clouds with tiny
width/height. It now draws straight lines instead of arcs if the arcs
are essentially flat, and it increases the number of lumps when width or
height are very small to avoid certain kinds of weirdness.

Text was wrapping on Safari because the measure text div was rendered
differently on different browsers. Interestingly, when forcing the
text-measure div to be visible and on-screen in Chrome, the same
text-wrapping behaviour was apparent. By setting white-space to 'pre'
when width hasn't been set by the user, we can ensure that only line
breaks the user has inputted are rendered by default on all browsers.

This PR removes the automatic focus events from the editor.
The `autoFocus` prop is now true by default. When true, the editor will
begin in a focused state (`editor.instanceState.isFocused` will be
`true`) and the component will respond to keyboard shortcuts and other
interactions. When false, the editor will begin in an unfocused state
and not respond to keyboard interactions.
**It's now up to the developer** using the component to update
`isFocused` themselves. There's no predictable way to do that on our
side, so we leave it to the developer to decide when to turn on or off
focus for a container (for example, using an intersection observer to
"unfocus" components that are off screen).
### Change Type

This PR has been tested on Mac Chrome, iOS Safari, and Android Chrome.
---
This PR removes 'targeted editing' from text.
This affects when you're:
* using the text tool
* editing a text shape
* editing a text label
* editing an arrow label
When in one of these modes, you were able to click on some other text to
immediately start editing it (as long as that text is the same type).
It was a bit broken with some of the newer changes, so this PR removes
it. The issues included:
* selected text 'flashing'
* caret going to the start of the text
* empty text shapes not disappearing
* inconsistent behaviour when clicking near a shape VS on a shape
It feels a bit simpler now too, I like it... 🤔💭

### Change Type
- [x] `patch` — Bug fix
This PR makes it so that user preferences can be in a 'null' state,
where we use the default values and/or infer from the system
preferences.
Before this PR it was impossible to allow a user to change their locale
via their system config rather than selecting an explicit value in the
tldraw editor menu. Similarly, it was impossible to adapt to changes in
the user's system preferences for dark/light mode.
That's because we saved the full user preference values the first time
the user loaded tldraw, and the only way for them to change after that
is by saving new values.
After this PR, if a value is `null` we will use the 'default' version of
it, which can be inferred based on the user's system preferences in the
case of dark mode, locale, and animation speed. Then if the user changes
their system config and refreshes the page their changes should be
picked up by tldraw where they previously wouldn't have been.
Dark mode inference is opt-in by setting a prop `inferDarkMode: true` on
the `Editor` instance (and the `<Tldraw />` components), because we
don't want it to be a surprise for existing library users.

When we begin drawing a line it's nice for the user to be able to see a
dot, so we put down two points. The end point for a new line was set to
the same position as the first point, which was causing a bunch of
divide by zero errors. Offsetting it slightly fixes that.
Now when two handles are too close together we extend the second one
instead of drawing a third. This will probably only ever happen with the
first two points of a line.

[^1]: publishes a `patch` release, for devDependencies use `internal`
[^2]: will not publish a new version
This last day or two our npm publish script has been randomly failing
due to npm flakiness. I'm seeing the following error:
Failed to save packument. A common cause is if you try to publish a new
package before the previous package has been fully processed.
This doesn't seem to be our fault since we're publishing things in the
right order, the version numbers and package.json files are all correct,
and we're waiting for things to appear in the registry after publishing
before moving on to the next package.
So I'm thinking maybe npm is a little tired right now or something and
needs a little extra time to handle things.
So I've wrapped our publish command inside a retry block.
At the same time I noticed that the `--tolerate-republish` flag does not
seem to be working for canary version numbers, so I've added some extra
logic for that too. Hopefully this means if things fail due to
persistent npm flake we can just run the action again.

Previously, if a shape had two frame parents and those frames didn't
intersect, we'd render the shape without any clipping. This is because
in the case that we don't find an intersection we were returning
undefined (meaning nothing is masked out) instead of an empty array
(meaning everything is masked out)

Currently, the highlighter shape uses a single 0-width line for its
geometry, same as the draw tool. For the draw tool this works ok - the
visual line is thin enough that unless you zoom right in, it's hard to
find areas where the hover should trigger but isn't. As the highlighter
tool is much thicker though, it's relatively easy to find those areas.
The fix is for the geometry to represent the line including its thick
stroke, instead of at 0-width. There are two possible approaches here:
1. Update the polyline geometry to allow passing a stroke width.
2. Instead of a polyline, make the highlighter shape be a polygon that
traces _around_ the stroke
1 is the more accurate approach, but is hard to fit into our geometry
system. Our geometry is based around two primitives: `getVertices` which
returns an array of points around the shape, and `nearestPoint` which
returns the nearest point on the geometry to a vector we pass in. We can
account for a stroke in `nearestPoint` pretty easily, including it in
`getVertices` is hard - we'd have to expand the vertices and handle line
join/caps etc. Just making the change in `nearestPoint` does fix the
issue here, but i'm not sure about the knock-on effect elsewhere and
don't really want to introduce 1-off hacks into the core geometry
system.
2 actually means addressing the same hard problem around outlining
strokes as 1, but it lets us do it in a more tightly-scoped one-off
change just to the highlighter shape, instead of trying to come up with
a generic solution for the whole geometry system. This is the approach
I've taken in this diff. We outline the stroke using perfect-freehand,
which works pretty well but produces inaccurate results at edge-cases,
particularly when a line rapidly changes direction:

01](https://github.com/tldraw/tldraw/assets/1489520/1593ac5c-e7db-4360-b97d-ba66cdfb5498)
I think that given this is scoped to just the highlighter shape and is
imo an improvement over the stroke issue from before, it's a reasonable
solution for now. If we want to in the future we could implement real
non-freehand-based outlining.

For example, pasting text sometimes incudes additional clipboard items,
such as the HTML representation of that text. We wouldn't want to create
two shapes—one for the text and one for the HTML—so we still treat this
as a single text paste. The `registerExternalContentHandler` API allows
a developer to change how that text is handled, and the new `sources`
API will now allow the developer to take into consideration all of the
items that were on the clipboard.
