A minimized window may not be associated with any displays, so check that the output array is valid and that there is at least one associated display before dereferencing.
Fixes a crash when attempting to unset fullscreen on a minimized window.
For GTK-based systems using XSETTINGS it's much more likely to be
available, rather than the "GDK_SCALE" environment variable, which is a
debugging tool according to the GTK documentation.
Import the XSettingsClient implementation to handle the settings
selection.
Currently, we only care about the Gdk/WindowScalingFactor value used by
the windowing system to notify us of display-wide changes in the scaling
factor.
If XInput2 is enabled, it will grab the pointer on button presses, which results in XGrabPointer returning AlreadyGrabbed. Clear any existing grabs before attempting the confinement grab to avoid a timeout scenario.
This fixes numerous problems regarding dead keys on Wayland. Most notably, Wayland was enforcing dead keys on SDL_KEYDOWN and SDL_KEYUP events, which caused unresponsiveness on keys that were mapped to dead keys (tilde on US-Intl is most notable for this, commonly used as a console key).
When starting text input, not all state was reset properly. The text input protocol requires to be re-enabled every time text input changes, which SDL did not do. Also, XKB compose state was not reset at all, causing composite and dead keys to carry over from when text input was disabled.

This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.
This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.
Fixes#9902.
(and several FIXMEs, both known and yet-undocumented.)
Borderless windows flagged as fullscreen at creation time turn on the borders, because doing so prevents some window managers from wrongly positioning the borderless window, and in these cases the borders need to be removed whether fullscreen is exited programmatically or via a compositor event. Set a flag when forcing the borders on, so they will be removed in all cases later.

This reverts commit 2de2e9d031.
The fullscreen state is no longer available to check, and the actual bug this was trying to work around was fixed in ad813a65e7
Note that Wayland places a restriction on windows being resized, where the requested size passed to the configuration event is a maximum, and attempting to exceed it is a protocol violation, so trying to grow the window by dragging the sides only vertically or horizontally is limited, as the provided dimensions can't be exceeded.
In practice, nothing seems to kill clients that do this, but the more immediate problem is that doing so causes GNOME to glitch out.
The HDR properties are zeroed and set in WIN_GetHDRProperties, and using the struct without calling this function results in sending uninitialized data.

The wp_alpha_modifier_v1 protocol allows for a global blending factor to be specified for an entire surface. Use this to add support for SDL_SetWindowOpacity().
In some cases, size data set programmatically could be overwritten by old configuration data, particularly when on the display scaling path. This refactors the configuration code to be much more strict and verbose regarding the handling of window sizes, which fixes some scenarios where tests were failing when display scaling was activated.
