- This allows looking up the display index for an arbitrary location rather than requiring an active window to do so.
- This change also reimplements the fallback display lookup that found the display with center closest to the window's center to instead find the display rect edge
closest to the window center (this was done in the almost identical display lookup used in SDL_windowsmodes.c, which now uses `SDL_GetPointDisplayIndex`). In
practice this should almost never be hit as it requires the window's center to not be enclosed by any display rect.
The current method of toggling the libdecor window visibility by destroying and recreating the frame results in a race where a use-after-free bug can manifest itself within libdecor when window visibility is toggled quickly. Instead, use the libdecor function for toggling visibility instead of destroying and recreating the frame every time.
Wayland works like SDL's "auto capture" feature already, tracking the mouse
globally only while a drag is occuring, and this is the only way to get mouse
input outside the window.
Setting this flag ourselves lets SDL_CaptureMouse() work in the most common
use case without actually implementing CaptureMouse for the backend, including
SDL's auto capture feature.
Fixes#6010.
GNOME exposes the cursor size and theme via the org.freedesktop.portal.Settings interface of the xdg-desktop portal, so query these values via D-Bus, if available.
The XCURSOR_SIZE/XCURSOR_THEME envvars will be tried first, so as not to override any user specified sizes or themes, then D-Bus, then, failing that, it will fall back to default values.
The event no longer spams each time a window gets focus if there are windows on monitors with different color profiles.
This also has the side effect that you no longer get a color profile event at window creation, which is consistent with other events that communicate state changes.
- Touch events may be translated to mouse movement events without the normal Xinput2 raw motion events
being sent. Not all touch events will necessarily move the mouse but this ensures we update the global
mouse state just in case.
- Fix up some formatting
CR: saml
Cache off NSWindow's windowNumber in SDL_WindowData on setup and use that in `Cocoa_SendWakeupEvent` to prevent accessing windowNumber off the main thread.
As discussed in PR review, there may be an off-chance that the index
returned doesn't match up with SDL's display indexing.
This change ensures that the indices match and adds a safety check for
off-screen windows.
With the introduction of this function, it is possible that for certain
monitor and window configurations, creating an SDL window will cause a
native crash.

In testing, the window would not find a valid screen if created
"hanging" off a primary display with a secondary display below it. In
checking why this was the case, the `display_centre` was being
calculated with a negative y origin, causing a final negative value
falling outside all display bounds:
```
SDL error log [debug]: display_centre.y = -1296 + 1296 / 2
SDL error log [debug]: Display rect 0: 0 0 2560 1440
SDL error log [debug]: Display rect 1: 2560 -625 1080 2560
SDL error log [debug]: Display rect 2: 0 1440 1728 1296
```
The method that was being used to find the current window using the frame
origin/size seems unreliable, so I have opted to replace it with with a
tried method (https://stackoverflow.com/a/40891902).
Initial testing shows that this works with non-standard DPI screens, but
further testing would be appreciated (cc @sezero / @misl6 from the
original PR thread).
We actually request CSD mode with xdg-decoration for borderless
windows, so we get what we wanted there and there's no point in going
into fallback paths.
