### Problem
After transitioning Zed to GPUI 2, we started noticing that interacting
with the mouse on many UI elements would lead to a pretty annoying
flicker. The main issue with the old approach was that hover state was
calculated based on the previous frame. That is, when computing whether
a given element was hovered in the current frame, we would use
information about the same element in the previous frame.
However, inspecting the previous frame tells us very little about what
should be hovered in the current frame, as elements in the current frame
may have changed significantly.
### Solution
This pull request's main contribution is the introduction of a new
`after_layout` phase when redrawing the window. The key idea is that
we'll give every element a chance to register a hitbox (see
`ElementContext::insert_hitbox`) before painting anything. Then, during
the `paint` phase, elements can determine whether they're the topmost
and draw their hover state accordingly.
We are also removing the ability to give an arbitrary z-index to
elements. Instead, we will follow the much simpler painter's algorithm.
That is, an element that gets painted after will be drawn on top of an
element that got painted earlier. Elements can still escape their
current "stacking context" by using the new `ElementContext::defer_draw`
method (see `Overlay` for an example). Elements drawn using this method
will still be logically considered as being children of their original
parent (for keybinding, focus and cache invalidation purposes) but their
layout and paint passes will be deferred until the currently-drawn
element is done.
With these changes we also reworked geometry batching within the
`Scene`. The new approach uses an AABB tree to determine geometry
occlusion, which allows the GPU to render non-overlapping geometry in
parallel.
### Performance
Performance is slightly better than on `main` even though this new
approach is more correct and we're maintaining an extra data structure
(the AABB tree).

Release Notes:
- Fixed a bug that was causing popovers to flicker.

This solves a major usability problem in Zed, that there's no way to
temporarily disable auto formatting without toggling the whole feature
off.
fixes https://github.com/zed-industries/zed/issues/5230
Release Notes:
- Added a new `workspace::SaveWithoutFormatting`, bound to `cmd-k s`, to
save a file without invoking the auto formatter.
Release Notes:
- Added
[`:tabo[nly][!]`](https://neovim.io/doc/user/tabpage.html#%3Atabonly),
closes all the tabs except the active one but in the current pane only,
every other split pane remains unaffected.
The version with the `!` force closes the tabs while the one without
asks you to save or discard the changes.
- Added [`:on[ly][!]`](https://neovim.io/doc/user/windows.html#%3Aonly),
closes all the tabs *and* panes except the active one.
The version with the `!` force closes the tabs while the one without
asks you to save or discard the changes.
Since Zed does not have different splits per tab like in Neovim `:only`
works the same as it does in VscodeVim.

Previously it wasn't possible to create a keybinding for this action
because it required an argument.
Now the action takes the active item of the pane and if it's a
multi-buffer the first one.
This also adds a default keybinding for Vim mode: `-` will reveal the
file in the project panel.
Fixes#7485.
Release Notes:
- Added `pane::RevealInProjectPanel` as an action in the command
palette. ([#7485](https://github.com/zed-industries/zed/issues/7485)).

This time around, we address the flicker seen in #3857 by querying the active item (that might've just been added),
as it knows whether it has focus even if the parent Pane does not.

This fixes https://github.com/zed-industries/community/issues/2442 for
me.
Previously, the tab bar buttons would stay when the chat panel was
opened (and received focus) until something else was drawn (or caused a
render?)
With this change, the tab bar buttons are only shown if the pane was
focus.
I'm not sure about the side-effects of this, but the toolbar still seems
to work fine.
This adjusts the solution in
https://github.com/zed-industries/zed/pull/4014 to fix the double-focus
issue, allowing each pane's project search to work independently.
Release Notes:
- Changed the name of the `workspace::DeploySearch` action to
`pane::DeploySearch` and changed it's behavior to open a new search OR
focus an existing project search in the current pane.

This PR renames the `h_stack` and `v_stack` to `h_flex` and `v_flex`,
respectively.
We were previously using `h_stack` and `v_stack` to match SwiftUI, but
`h_flex` and `v_flex` fit better with the web/flexbox terminology that
the rest of GPUI uses.
Additionally, we were already calling the utility functions used to
implement `h_stack` and `v_stack` by the new names.
Release Notes:
- N/A
This PR renames the `IconElement` component to just `Icon`.
This better matches the rest of our components, as `IconElement` was the
only one using this naming convention.
The `Icon` enum has been renamed to `IconName` to free up the name.
I was trying to come up with a way that would allow rendering an
`Icon::Zed` directly (and thus make the `IconElement` a hidden part of
the API), but I couldn't come up with a way to do this cleanly.
Release Notes:
- N/A
* gitignored entries are never auto revealed
* `project_panel::auto_reveal_entries = true` settings entry was added,
setting it to `false` will disable the auto reveal
* `pane::RevealInProjectPanel` action was added that activates the project panel and reveals the entry it got triggered on (including the gitignored ones)
