This change ensures that we always render a window according to its
refresh rate, even if there are a lot of X11 events.
We're working around some limitations of `calloop`. In the future, we
think we should revisit how the event loop is implemented on X11, so
that we can ensure proper prioritization of input events vs. rendering.

I'm not sure where exactly that error comes from, except from the X11
stuff. So let's be defensive and log error and only then tear down
everything.
I _think_ that if the error is repeatable that means we won't close the
window but instead just log errors, but I do think that's better than
panicking right now.

Fixes https://github.com/zed-industries/zed/issues/12054
Replaces the `copypasta`/`smithay-clipboard` implementation with a new,
custom one
TODO list:
- [x] Cleanup code
- [x] Remove `smithay-clipboard`
- [x] Add more mime types to the supported list
Release Notes:
- Fixed drag and drop on Gnome
- Fixed clipboard paste on Hyprland
This fixes everything but the main Zed window (GPUI examples, prompt
library, etc.) not being closable by clicking on the X in X11.
We had a dangling reference before: we would remove the window from the
X11 state, but GPUI itself would still have the window in its
references.
In order to fix this we have to call `window.close()`, which ends up
calling `cx.remove_window()`, which removes the reference.
That in turn then causes the reference to be dropped, which cleans up
the X11 state for the window.
Release Notes:
- N/A
On most platforms, things were working correctly, but had the wrong
type. On X11, there were some problems with window and display size
calculations.

Turns out we still get FocusOut and UnmapNotify events after the window
has been destroyed, which resulted in error messages popping up because
we can't find the window anymore that we want to mark as unfocused.
Release Notes:
- N/A
I noticed that when I use my mouse wheel, we get a ton of the
`XkbStateNotify` events, but the modifiers don't change, so we add a ton
of useless input events for the window.
Release Notes:
- N/A
This helps with the problem of keyboard input feeling laggy when the
event loop is under load.
What would previously happen is:
- N events from X11 arrive
- N events get forwarded to XIM
- N events are handled in N iterations of the event loop (sadly, yes: we
only seem to be getting back one `ClientMessage` per poll from XCB
connection)
- Each event is pushed into the channel
- N event loop iterations are needed to get the events off the channel
and handle them
With this change, we get rid of the last 2 steps: instead of pushing the
event onto a channel, we store it on the XIM handler itself, and then
work it off synchronously.
Usually one shouldn't block the event loop, but I think in this case -
user input! - it's better to handle the events directly instead of
re-enqueuing them again in a channel, where they can accumulate and need
multiple iterations of the loop to be worked off.
This does *not* fix the problem of input feeling choppy/slower when the
system is under load, but it makes the behavior now feel exactly the
same as when XIM is disabled.
I also think the code is easier to understand since it's more
straightforward.
Release Notes:
- N/A
This change ensures that the event loop prioritizes enqueueing another
render or handling user input over executing runnables.
It's a subtle change as a result of a week of digging into performance
on X11. It's also not perfect: ideally we'd get rid of the intermediate
channel here and had more control over when and how we run runnables vs.
X11 events, but I think short of rewriting how we use an event loop,
this is good cost/benefit change.
To illustrate:
Before this change, it was possible to block the app from rendering for
a long time by just creating a ton of futures that were executed on the
"main" thread (we don't have a "main" thread on Linux, but we have a
single thread in which we run the event loop).
That was relatively easy to reproduce by opening the `zed` repository
and starting `rust-analyzer`: at some point `rust-analyzer` sends us so
many notifications, that are all handled in futures, that the event loop
is busy just working off the runnables, never getting to the events that
X11 sends us or our own timer to re-enqueue another render.
When you put print statements into the code to show when which event was
handled, you'd see something like this **before this change**:
```

```
Note the `lag: 56ms`: that's the difference between when we wanted to
execute the callback that enqueues another render and when it ran.
Longer lags are possible, this is just the first one I grabbed from the
logs.
Now, compare this with the logs **after this change**:
```

```
In-between many `runnable.run()` we'll always handle events.
So, in essence, what this change does is to introduce 2 priorities into
the X11 event queue:
- high: X11 events (user events, render events, ...), render tick, XIM
events, ...
- low: all async rust code
I've tested this with a debug build and release build and I think the
app now feels more responsive. It doesn't feel perfect still, especially
in the slow debug builds, but I couldn't observe 10s lockups anymore.
Since it's a pretty small change, I think we should go for it and see
how it behaves.
Thanks to @maan2003 this now also includes the same change to Wayland.

This fixes#11236 by ignoring the `bounds.origin` values when the window
is only being resized.
The cause for the issue was that the `ConfigureNotify` event would
contain "wrong" values when the window was being resized (by dragging a
corner).
In my case it would *always* contain x:14/y:49, which is I think might
map to the origin of the top bar in GNOME.
We would then persist these wrong values when serializing the workspace.
On restart, we'd use these values and end up with the window decorations
in the wrong place.
What I still don't know:
1. What exactly the 14/49 map to, because it's not the origin of the top
bar in GNOME. I also tried the X11 TranslateCoordinates call but
couldn't get meaningful results back (even taking scale factor into
account).
2. Why the window decorations end up looking wrong vs. the window being
in the first place. But if you look at my screenshot in #11236, it looks
like the decorations are off exactly by 14/49px.
That being said, I think the solution here is a good one for now: we
don't do an additional X11 call and when we're resizing, we're not
interested in the origin changing.

This (mostly) allows the CSD added in
https://github.com/zed-industries/zed/pull/11525 to work in X11. It's
still a bit buggy as it detects a second window drag right after the
first one finishes, but it's probably better to change the way window
drags are detected in the title bar itself (as that causes other
issues).
The CSD can be tested by changing the return value of
`should_render_window_controls` to true.
Also fixes F11 crashing.

This pull request adds XIM (X Input Method) support to x11 platform.
The implementation utilizes [xim-rs](https://crates.io/crates/xim), a

Preedit and candidate positioning are fully supported in the editor
interface, yet notably absent in the terminal environment.

Now, regardless of how the Zed window is closed, Zed can remember the
window's restore size.
- [x] Windows implementation
- [x] macOS implementation
- [x] Linux implementation (partial)
- [x] update SQL data base (mark column `fullscreen` as deprecated)
The current implementation on Linux is basic, and I'm not sure if it's
correct.
The variable `fullscreen` in SQL can be removed, but I'm unsure how to
do it.
edit: mark `fullscreen` as deprecated
### Case 1
When the window is closed as maximized, reopening it will open in the
maximized state, and returning from maximized state will restore the
position and size it had when it was maximized.
https://github.com/zed-industries/zed/assets/14981363/7207752e-878a-4d43-93a7-41ad1fdb3a06
### Case 2
When the window is closed as fullscreen, reopening it will open in
fullscreen mode, and toggling fullscreen will restore the position and
size it had when it entered fullscreen (note that the fullscreen
application was not recorded in the video, showing a black screen, but
it had actually entered fullscreen mode).
https://github.com/zed-industries/zed/assets/14981363/ea5aa70d-b296-462a-afb3-4c3372883ea3
### What's more
- As English is not my native language, some variable and struct names
may need to be modified to match their actual meaning.
- I am not familiar with the APIs related to macOS and Linux, so
implementation for these two platforms has not been done for now.
- Any suggestions and ideas are welcome.

This PR replaces all pointer events on X11 with their XI2 equivalents,
which fixes problems with scroll events not being reported when a mouse
button is down. Additionally it closes#11206 by resetting the tracked
global scroll valulator position with `None` on a leave event to prevent
a large scroll delta if scrolling is done outside the window. Lastly, it
resolves the bad window issue kvark was having.
Release Notes:
- Fixed X11 Scroll snapping (#11206 ).

Since Wayland doesn't have a way for windows to activate themselves,
currently, when you click on a link in Zed, the browser window opens in
the background.

This should have fixed the problems that some users were reporting with
https://github.com/zed-industries/zed/pull/10695 .
The problem was with devices which send more than one valuator axis in a
single event whereas the original PR assumed there would only ever be
one axis per event. This version also does away with the complicated
device selection and instead just uses the master pointer device, which
automatically uses all sub-pointers.
Edit: Confirmed working for one of the user's which the first attempt
was broken for.
Release Notes:
- Added smooth scrolling for X11 on Linux
- Added horizontal scrolling for X11 on Linux
fixes https://github.com/zed-industries/zed/issues/9132
By setting the app id, window managers like `sway` can apply custom
configuration like `for_window [app_id="zed"] floating enable`.
Tested using `wlprop`/`hyprctl activewindow` for wayland, `xprop` for
x11.
Release Notes:
- Zed now sets the window app id / class, which can be used e.g. in
window managers like `sway`/`i3` to define custom rules

Changes the X11 platform code to use the xinput extension which allows
for smooth scrolling and horizontal scrolling.
Release Notes:
- Added smooth scrolling to X11 on Linux
- Added horizontal scrolling to X11 on Linux
This fixes certain shortcuts/motions on X11 like in vim mode "v i )",
where previously zed would interpret it as "v i SHIFT )" due to the x11
backend emitting key press events for modifier keys even though other
platforms like Wayland don't. This also adds support for
ModifiersChanged events to X11
Release Notes:
- Fixed vim motions like "v i )" not working on X11
([#10199](https://github.com/zed-industries/zed/issues/10199)).
This puts the Linux platform implementation at a similar code style and
quality to the macOS platform. The largest change is that I collapsed
the `LinuxPlatform` -> `[Backend]` -> `[Backend]State` ->
`[Backend]StateInner` to just `[Backend]` and `[Backend]State`, and in
the process removed most of the `Rc`s and `RefCell`s.
TODO:
- [x] Make sure that this is on-par with the existing implementation
- [x] Review in detail, now that the large changes are done.
- [ ] Update the roadmap
Release Notes:

Sharing a project displays a notification (window) on every screen.
Previously there was an issue with the positioning of windows on all
screens except the primary screen.
As you can see here:
Now:
@mikayla-maki and I also decided to refactor the `WindowOptions` a bit.
Previously you could specify bounds which controlled the positioning and
size of the window in the global coordinate space, while also providing
a display id (which screen to show the window on). This can lead to
unusual behavior because you could theoretically specify a global bound
which does not even belong to the display id which was provided.
Therefore we changed the api to this:
```rust
struct WindowOptions {
/// The bounds of the window in screen coordinates
/// None -> inherit, Some(bounds) -> set bounds.
pub bounds: Option<Bounds<DevicePixels>>,
/// The display to create the window on, if this is None,
/// the window will be created on the main display
pub display_id: Option<DisplayId>,
}
```
This lets you specify a display id, which maps to the screen where the
window should be created and bounds relative to the upper left of the
screen.
Release Notes:
- Fixed positioning of popup windows (e.g. when sharing a project) when
using multiple external displays.
