It happens fairly often that people enable X11 support but don't install the extension libraries that SDL depends on. This makes those required if not explicitly disabled, which should help prevent accidentally broken builds.
Recalculate the backing viewport dimensions in the resize handler, otherwise, this data can be out-of-sync with the logical window size if queried during transition animations.
This makes sure that anything that hooks window creation to set up window proc hooks will call DefWindowProc instead of infinitely recursing when we set up our window proc afterwards.

The controller can be in XInput mode or enhanced mode, so it will always show up as an XInput controller, and the enhanced mode controller will come and go as enhanced mode is enabled or disabled in the FlyDigi Space Station app.
Store the images in order from smallest to largest to simplify lookup and be able to early-out of the search loop even if there is no exact match for the scale.
Some compositors don't implicitly use the pointer cursor when the tablet cursor is not set, and the presence of a tablet doesn't necessarily guarantee pointer capability. Set the cursor for tablet tools independently of pointer cursors.
This required refactoring of cursor state handling, as well as some tablet related structures.
Cache the cursor image data at creation time, and use a viewport to render scaled custom cursors, instead of generating new cursor images for every scale.
The OS uses the presence of the UILaunchScreen key to determine whether to display the application in compatibility mode or display using the whole screen.
Allowing GCC/Clang to auto-vectorize with AltiVec support breaks support
for non-AltiVec compatible processors. Adding this option allows the
existing AltiVec specific code to function as it always did, but
prevents the compiler from inserting AltiVec instructions into arbitrary
codepaths that SDL can't gate off via the existing CPUInfo code.
pa_channel_map_init_auto() with PA_CHANNEL_MAP_WAVEEX does the wrong
thing as it just takes the lest significant bits of
WAVEFORMATEXTENSIBLE's dwChannelMask in order. This doesn't match SDL's
chosen channel ordering.
The implementation here mirrors what we do for PipeWire.
Setting AudioCategory_GameChat breaks audio on several devices, including Behringer U-PHORIA UM2 and RODE NT-USB Mini. We'll disable this for now until we understand more about what's happening.
This means we exercise the non-dlopen()-based code paths for these,
as used in Debian and the Steam Runtime.
