Previously, terminal mouse selection didn't work when the cursor moved
outside the bounds of the terminal, which made it difficult to select
large amounts of text in the terminal.

This fixes various actions like "Activate regex mode" that were dispatched onto main pane instead of assistant search bar.

This fixes various actions like "Activate regex mode" that were dispatched onto main pane instead of assistant search bar.

This commit adds a Registrar trait for use by search crate. Registrar can register actions on some target and search can utilize that trait to opaquely add actions on that target.
Notably, search is now opt-in (it always was in zed2 actually). Having editor doesn't make it searchable straight out of the gate. You might have to call BufferSearchBar::new a bunch more.

There are two issues with search in terminal as is:
- terminal's pane is not registered as a "legit" pane, so we dispatch buffer search bar::Deploy on the most recent "legit" pane. By legit I mean that
  workspace::active_pane will *never* return terminal pane as active.
- We've had the implementation of as_searchable commented out. Duh!

This commit fixes second issue. That means that if you drag the terminal over to the main editor pane (so that it's in a "legit" pane), it'll work. 1st issue still stands though.

This PR takes another pass at the collab panel filter input to improve
its styling.

Release Notes:

- Improved the look of the filter input in the collab panel.

This PR fixes an issue where certain tabs were not using the correct
color for their labels when they were inactive.

Release Notes:

- Fixed an issue where some inactive tabs were not using the correct
label color.

This PR makes it so when we're not showing file icons in the project
panel we render an empty placeholder instead of nothing.

This prevents the indentation of the items in the file tree from
changing based on the presence of the icon.

Release Notes:

- Fixed layout shift when `project_panel.file_icons` is set to `false`.

- `base_keymap` setting was not respected, now it is
- without a `~/.config/zed/keymap.json` file, we would fail to load the
*default* keymap

Previously it would both send the keydown *and then* the action, now
it send the action, and then because there was an action, does not send
the keydown

This PR updates the font resolution for shaped text to use the new
`resolve_font` method on the text system.

This makes it so we use the fallback font if the desired font cannot be
found rather than rendering nothing.

Release Notes:

- Fixed an issue where nothing would render when the font set in
`ui_font_family` was not found.

Add a `workspace::DeploySearch` action and use it as a default for "cmd-shift-f" binding.
This action opens existing search tab if it exists, or creates a new one otherwise.
`workspace::NewSearch` action is still available and always opens an existing search tab.

This PR adjusts our font resolution code to attempt to use a fallback
font if the specified font cannot be found.

Right now our fallback font stack is `Zed Mono`, followed by `Helvetica`
(in practice we should always be able to resolve `Zed Mono` since we
bundle it with the app).

In the future we'll want to surface the ability to set the fallback font
stack from GPUI consumers, and potentially even support specifying font
stacks in the user settings (as opposed to a single font family).

Release Notes:

- Fixed a panic when trying to load a font that could not be found.

the drag handle overlapped with an editor scrollbar.

Release Notes:

- Fixed a bug that caused `cmd-g` and `cmd-shift-g` to not work anymore
in the assistant panel.

After implementing it a while ago, our previous interpolation scheme
didn't really make sense to me and was causing borders to be rendered
incorrectly. We don't really draw backgrounds and borders as part of the
same draw call anymore, but it seemed reasonable to have a correct
implementation in the shader anyway.

This commit uses Porter-Duff compositing (i.e., `over`) to produce a
color that is the result of superimposing the border on top of the
background. Then, we linearly interpolate towards the background color
as we slide out of the border and into the background.

Release Notes:

- Fixed incorrect rendering of borders.
