libusb-1.0-0 is needed to enable SDL_HIDAPI_LIBUSB. It does not work with the `libusb-dev` package on Ubuntu, which is for the older version.
(cherry picked from commit c247f06f01)
Because the blend mode is explicitly set to SDL_BLENDMODE_NONE, it doesn't matter if there's a transparency channel in the texture format or not for opaque windows. This ensures that a 32-bit format is used with Metal instead of SDL_PIXELFORMAT_RGB565.

This fixes faults when loading from read-only memory and avoids
cache line bouncing across cores which reduces performance.

Now this keeps one FBO for each SDL_TEXTUREACCESS_TARGET texture, and doesn't
reuse it. We check if the FBO is "complete" once, at creation time, and
setting a render target merely has to bind the right FBO and never look back.
This simplifies the code and removes a guaranteed pipeline stall when setting
a new render target.
Fixes#15524.

Some compositors may dispatch this too early, during the initial empty commit, when subsurfaces are attached to a toplevel window, but a buffer has yet to be committed to the parent surface. Don't set the frame callback until the initial empty commit is done, so it will be called when the actual parent surface frame is committed.
(cherry picked from commit e3393e6304)
Some compositors send the frame callback as part of the initial configuration sequence, so the window may already be past the "waiting for frame" state. Ensure that the exposure event is always sent.

Under the right conditions, this extension can result is smoother resizing when rendering with OpenGL, however, it is known to cause problems in certain cases, such as when handling presentation externally.
Gate it behind a hint, and disable it by default. Developers can selectively enable it when they verify that they meet the criteria for using it, and that it behaves correctly in their apps/games.

If the cursor was created with a temporary surface that was pointing at external memory, then when the cursor is used it might be referencing memory that had already been freed.
(cherry picked from commit f6f4664ed1)
This was added so that the new thread definitely has its threadid set, via
SDL_GetCurrentThreadID(), before SDL_CreatThread returns, but this broke
Emscripten, which can't wait on a newly-created thread, since the thread won't
start until a later mainloop iteration.
Now we have the creating thread set this id in SDL_SYS_CreateThread, where
platform-specific logic can figure out how to calculate the new thread's ID
from the parent thread, without using SDL_GetCurrentThreadID().
Fixes#15509.

Natural scrolling affects both axes, and the compositor may not send the vertical axis orientation if the frame has no vertical scroll motion, so purely horizontal events need to be flagged as inverted as well.

controller.vendorName returns a generic name for Xbox controllers ("Controller"), so we have to give them proper names.
