wl_compositor v6 introduces the preferred buffer scale event, which serves a similar function to the fractional scale protocol, but deals in integer scale factors. Listen to this event when the wl_compositor version is >= 6 and the fractional scale protocol is not present to set the scale factor for surfaces.
- Composited windows seem to need to actually paint (or appear to paint) through calls to Begin/EndPaint to properly validate
their update region. If not done they will continue to receive WM_PAINT messages for the same region.
When X11_UpdateWindowPosition() was called and the position didn't update
we would fire an SDL_EVENT_WINDOW_MOVED event with the global x,y for
the pop-up instead of the relative position for the pop-up.
This change ensures we always have a relative position for pop-ups before sending
the SDL_EVENT_WINDOW_MOVED event.
xdg-output names and descriptions are deprecated in favor of those provided by the core wl_output protocol as of v4. Bump wl_output support to v4 and ignore the xdg-output description in favor of the wl_output description when appropriate.
This allows clients to be aware of "natural scrolling" settings in the
compostior and adjust accordingly to optionally keep the same wheel and
trackpad behaviour accross platforms.
Testing using the "testmouse" example, behaviour in the demo is now the
same regardless of the compositor setting for scrolling.

Track the serial numbers of key events, mouse button presses, touch down events, tablet tool down events, and tablet button presses, and pass the serial, along with the seat, to the xdg-activation protocol when raising windows to increase the chances of it succeeding.
Don't perform a round trip when setting the minimized and maximized window states during initial window creation, as it will be done later in the window creation process.
When changing the fullscreen state and performing a roundtrip, more than one configure event can be sent before getting the event that changes the fullscreen state. Don't change the higher-level window state and avoid recursive calls back into the video system during these events.
According to the xdg-shell spec, xdg-toplevel min/max values are just hints, which compositors are free to ignore, and they often do so in several cases (usually when tiling, maximizing, or entering fullscreen). Even with the hints set, manually constraining the surface dimensions for non-maximized, non-fullscreen surfaces is required for consistent behavior.
In the case of maximized windows, the dimensions as specified in the configure event are non-negotiable and must be respected by the client, as not doing so is a protocol violation.
This also eliminates some redundant calls to set the libdecor resizable state, which can cause unnecessary commits internally.
It turns out there's a race condition on X11 where the window could be placed by the window manager while being placed by the application, so we need to have the initial position available at window creation.
The X11 driver uses scancodes derived from keysyms to map the scancodes for extended keys to the physical keyboard, however, this can be incorrect when using certain XKB options (e.g. caps:swapescape), which changes the keysyms emitted by certain keys, but does not imply that their scancodes or positions should be altered. Mark selected scancodes as being non-remappable so that their scancodes aren't changed by toggling XKB mapping options.
