23e3cbec20 Only call clipboard callbacks with mime types they expect 
Also clarified that returning NULL from a callback sends zero length data to the receiver, which should be able to handle that.

244ae39b30 Optimized the 16-bit -> 32-bit SSE pixel conversion 
Test code:
---
int main( int argc, char *argv[] )
{
    SDL_Surface *orig = SDL_LoadPNG("testyuv.png");
    SDL_Surface *surf16 = SDL_ConvertSurface(orig, SDL_PIXELFORMAT_RGB565);
    SDL_Surface *surf32 = SDL_ConvertSurface(surf16, SDL_PIXELFORMAT_ARGB8888);

    Uint64 then = SDL_GetTicks();
    for (int i = 0; i < 100000; ++i) {
        SDL_BlitSurface(surf16, NULL, surf32, NULL);
    }
    Uint64 now = SDL_GetTicks();
    SDL_Log("Blit took %d ms\n", (int)(now - then));
    return 0;
}
---

Results on my system:
BlitNtoN: Blit took 34522 ms
Blit_RGB565_32 (3 LUT): Blit took 9316 ms
Blit_RGB565_32 (1 LUT): Blit took 5268 ms
Blit_RGB565_32_SSE41: Blit took 1619 ms

8df057fafc iostream: Properly support the "x" mode for SDL_IOFromFile() 
The "x" mode for `fopen()` (open file only if it doesn't exist) used to
be a glibc-exclusive extension, but was later standardized in C11, and
is now also implemented as part of every other widely-used libc:

	* musl: https://git.musl-libc.org/cgit/musl/tree/src/stdio/__fmodeflags.c?id=0ccaf0572e9cccda2cced0f7ee659af4c1c6679a
	* Android Bionic / OpenBSD: 731631f300/libc/upstream-openbsd/lib/libc/stdio/flags.c (86)
	* Apple / FreeBSD: 63976b830a/stdio/FreeBSD/flags.c (L91-L92)

As a result, "x" has already been working on all our automatically
tested platforms that implement `SDL_IOFromFile()` via `fopen()`. So
all we'd be missing for proper support is a Windows implementation
using `CREATE_NEW`, and the documentation that this mode exists and is
intended to work.

49d51a0d3c Removed TEXTURETYPE_PALETTE_PIXELART 
This doesn't make any sense since the pixel art algorithm uses a box filter to get an average pixel value which isn't possible with indexed textures.

8824eace93 testautomation: Test SDL_snprintf() for doubles >LLONG_MAX and <ULLONG_MAX 
The uclibc version of SDL_snprintf() is currently limited to values
<ULLONG_MAX due to the `unsigned long long` cast in SDL_PrintFloat(),
but it makes sense to at least ensure that it does support the full
unsigned 64-bit range. This also covers the one defined case where a
32-bit MSVC build can't assume that _ftoul2_legacy() == _ftol2().

a864dcac25 Added support for using the GPU renderer as an offscreen renderer 
SDL_CreateGPURenderer() now allows passing in an existing GPU device and passing in a NULL window to create an offscreen renderer.

Also renamed SDL_SetRenderGPUState() to SDL_SetGPURenderState().

c81b4e8493 test: Space-separate arguments in as-installed tests' .test files 
The "as-installed" tests have metadata files in the .desktop-like format
used by gnome-desktop-testing, which uses a subset of shell syntax for
the Exec field. The list of arguments is represented as a
semicolon-separated list by CMake, but we need to convert that into a
space-separated list for the Exec field.

Strictly speaking we should be quoting the arguments with the equivalent
of Python's shlex.quote, but I couldn't find a way to do that in CMake,
and currently none of the tests have arguments that need quoting.

26dd4e3abb Fixed filesystem operations on Android 
Full paths are used as-is, relative paths are prepended with SDL_GetAndroidInternalStoragePath(), and operations fall back to the asset system as appropriate.

This is consistent with the behavior of opening files on Android.
