If the system doesn't have Zenity installed, message boxes can fall back to the X11 toolkit while the Wayland driver is in use, in which case, a Wayland window may be set as a parent to an X11 dialog. Ensure that the parent window for an X11 dialog is actually an X11 window.
Adds support for animated cursors on Cocoa, Wayland, Win32, and X11.
testcursor can take a semicolon separated list of filenames and load an animated cursor from them.
Detect times that cross forward/backward across the zero timepoint, and handle them appropriately, so that events with an old timestamp don't mangle the time base offset, or have their timestamps mangled.
SDL_PumpEvents() was freeing the temporary memory in the clipboard event, so if the application was iterating over the mime types in the event and retrieving the clipboard data, it would crash after the first entry.
On Android, if you create a window with SDL_WINDOW_OPENGL, you can't create a Vulkan surface. The error message has been improved to reflect this, and the error is propagated back up to the application.
Also added warn level logging if the renderer couldn't be created.
This was added in 2016, presumably to help address the move/resize issues on Windows, which have been since been addressed by the live-resize functionality.

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
This beats the previous 3-LUT version and even beats SSE on my system.

While in a modal loop, the size in WM_WINDOWPOSCHANGING/WM_WINDOWPOSCHANGED may only be updated if the window is being resized interactively. Set the SWP_NOSIZE flag if the size hasn't changed from the last move/size event, or a size set programmatically may end up being overwritten by old size data.
