For some reason this locks up the Windows compositor when called by Steam. I'm disabling it for now until we understand why and whether this can cause issues for other applications as well.

The window failing to enter/exit fullscreen notifications don't necessarily imply anything about the actual state of the window. On failure, dump pending events, and don't presume anything about the current window state, as it will be handled by subsequent enter/leave notifications.

SDL still manages hotplug and default device management here, but if a user
wants to use an external tool, such as `pactl move-sink-input`, to put it
onto a different device, they probably know what they're doing and we
shouldn't stop them.
If this turns out to have some unexpected consequences, though, we can revisit
the change.

Otherwise, in the time it takes the thread to start and other init tasks to
complete, we tend to get an underrun on some systems, which ALSA logs to
stderr.
So this is moved to an InitThread implementation, which runs from the device
thread, right before it begins its main loop.

This prevents the waste of an initial buffer of audio on many backends, and is
hopefully harmless on all of them.

GNOME requires this to allow keyboard grabs on XWayland. Otherwise, XGrabKeyboard will still report success, but shortcuts won't be inhibited.

The accelerated relative coordinates are always relative to the desktop resolution, and need to be scaled with emulated fullscreen resolutions for mouse movement to remain stable. Otherwise, pointer speeds will be too fast on emulated resolutions below the desktop resolution, and too slow on those above.

The GPU API doesn't currently support transparent windows (transparent swapchain effects doesn't seem possible on D3D12) so we should explicitly fail so users don't expect transparency and then not get it.

We can't use keyboard input as a signal about whether a keyboard is attached. There might be keyboard input from any number of generated inputs or non-keyboard devices.

The tm_gmtoff field of the broken-down time 'tm' struct wasn't formally standardized until POSIX.1-2024, but practically it has been available on desktop *nix platforms such as Linux/glibc, FreeBSD, OpenBSD, NetBSD, OSX/macOS (NextStep before that), and others since the 1990s. The notable exception is SunOS/Solaris, where the timezone offset must still be retrieved in the strictly POSIX.1-2008 compliant way.

Some backends can't actually position a window until it is shown/mapped, so assume that it will be where it was asked to be as long as it is hidden.

On Windows 11, apparently HidD_GetManufacturerString() and HidD_GetProductString() can return TRUE without actually filling in any string data.
