It doesn't work well with Vulkan, and Vulkan windows may not have the Vulkan flag set in all circumstances, so only enable it if we explicitly know that OpenGL is being requested instead.

The default should be the entrypoint generated by SDL_shadercross. That way it doesn't need to be hand-specified in the common workflow.

On non-compositing window managers, XIconifyWindow can trigger map/unmap events, which would toggle the window hidden/shown state. This should not be done, as a hidden window in SDL is equivalent to a withdrawn window in X, and SDL will try to set/reset state when it is shown again.
Unless the window is explicitly being withdrawn via X11_HideWindow(), set unmapped windows to the minimized/occluded state, and send a restored event when mapped again.

This hint needs to persist outside of the normal application flow, so use the environment to set the initial value, and then save the value set via SDL_SetHint() after that.

External windows often handle their own events, and SDL implicitly processing events during synchronization can be unexpected and cause issues. For requests that don't change the window state beyond size or position, use the legacy synchronization method that synthesizes events from the window attributes without processing events.

this was causing problems when i was specifying non-zero buffer slots in
`SDL_BindGPUVertexBuffers`, `SDL_GPUVertexAttribute` and
`SDL_GPUVertexBufferDescription`.
`firstSlot + 1` is simply copied over from metal and d3d12 backends.

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.
