Also, it looks like using a u64 directly doesn't work well with Metal
shaders, so we unpack the u64 into two u32s.

Note how the line with rust analyzer error does not have a git diff
hunk.

Release Notes:
- N/A

Before this change the views would continue to update in the background
of the "disconnected" dialogue, which was disconcerting.

With this, we're done all known things that need porting.

there was no way to restart the audio stream.

Although it's not super clear why this fails; in zed1 we used to have a
bounds
check. Restoring the bounds check for now, but leaving a debug_assert!
in case
a local reproduction happens.

Release Notes:

- Fix a panic that happened sometimes when rendering folds

That hopefully helps with call notifications sometimes not being closed

We think this may fix a segfault that sometimes occurs during
`display_layer`.

This reverts commit 1c1151a0ed2f26ea2cf637aa4d07567ab6b4f372.

As part of debugging the port of following tests we added an assertion
that the project was dropped. Now that we initialize the editor and
handle focus correctly in tests, the project is retained by
`refresh_document_highlights`. That doesn't affect the meaning of the
tests

The culprit was in display map which was resolving next valid point for
the editor, without regard for whether that point belongs to the same excerpt. We now make an end point a minimum of the end point passed in and the start of excerpt header, if there are any. 
This bug existed in Zed1 as well.

Fixes: Diff markers in multibuffer search overlap with dividers between

views.

Welcome to the party!

This PR updates the `IconButton`s used to control the buffer search
options to use the `.selected` state to denote when they are active.
This matches what we are doing in the project search.

This should improve the contrast in certain themes.

Release Notes:

- Improved the active style for the search options in buffer search.

This PR fixes a number of places where we were incorrectly using "it's"
where we needed to use the possessive "its".

Release Notes:

- N/A

This reduces size of release binary by ~20% from 134MB to 107MB without noticeable slowdown on startup. Assets are decompressed granularly, on first access

Release Notes:

- Fixed theme selector not showing currently selected theme on open
