Otherwise we'll miss it when XWarpPointer() is used. x11vnc may do this to
manage mouse input in some circumstances, so it can be possible for _all_
mouse motion to go through this path, breaking SDL_GetGlobalMouseState().
Thanks to @chrismile for all the detective work to figure this out!
Fixes#8827.
These are faster and more precise.
This did not change the Uint16 versions (as SDL3 dropped them, and honestly
no one should be using them in SDL2), nor the NEON converters (as this was
not changed in SDL3, so far).
Fixes#8786.
Matches the one in `GetMouseMessageSource()`.
From my testing on Windows 11, the lower 8 bits in touch events cycle
trough the values 0x8c-0x95 in order.

like SDL_triangle.c:305:30: runtime error: left shift of negative value -672
(even if the value was correctly computed)
(cherry picked from commit 4033a0a83b)
The previous code was working incorrectly on viewports not having the
top left corner on the origin: even in those cases we only need to look
at the width and height of the viewport, because the drawing coordinates
are translated.
Fixes#8828
Unlike the test images in the previous commit, this one is
4-bytes-per-pixel RGBA32, so the masks used here appear to be correct
for both endiannesses. Converting it to SDL_PIXELFORMAT_RGBA32 just
makes it more concise.

All of these test images are provided as an octal dump of
3-bytes-per-pixel data with red, green and blue bytes in that order,
referred to as RGB24 in SDL's taxonomy. However, the call to
SDL_CreateRGBSurfaceFrom() used masks that would have been appropriate
for RGBA32 data.
On little-endian platforms, the test images loaded as intended anyway,
because SDL does not actually check all four masks before deciding to
use RGB24 (it only looks at the red mask), and the red channel happens to
be in the 0x000000FF position for both RGB24 and RGBA32 on little-endian.
Unfortunately, on big-endian platforms, the required masks are not the
same and the call failed with "Unknown pixel format". As far as I can
tell, this means testautomation_surface has never succeeded on big-endian
platforms, but presumably nobody has tried to run it on such platforms
until now.
In the SDL 3 branch, this was fixed as a side-effect of commit
932f6134 "Remove mask versions of SDL_CreateRGBSurface* #6701 (#6711)",
which I have used as a reference to confirm that RGB24 is correct.

When a test has been disabled because it's known not to work reliably
or it's a test for unimplemented functionality, we probably don't want
to encourage developers and testers to run it and report its failures
as a bug.

The udev container issue is mostly to do with device notifications
and netlink. The device classification stuff just pokes file in /sys
and /run/udev. Doesn't hurt to try it first for classifying joysticks
and then fall to the guess heuristics if it fails.
Added support for getting the real controller info, as well as the function SDL_GameControllerGetSteamHandle() to get the Steam Input API handle, from the virtual gamepads provided by Steam.
Also added an event SDL_CONTROLLERSTEAMHANDLEUPDATED which is triggered when a controller's API handle changes, e.g. the controllers were reassigned slots in the Steam UI.
