Simplified SDL_Surface
...
SDL_Surface has been simplified and internal details are no longer in the public structure.
The `format` member of SDL_Surface is now an enumerated pixel format value. You can get the full details of the pixel format by calling `SDL_GetPixelFormatDetails(surface->format)`. You can get the palette associated with the surface by calling SDL_GetSurfacePalette(). You can get the clip rectangle by calling SDL_GetSurfaceClipRect().
SDL_PixelFormat has been renamed SDL_PixelFormatDetails and just describes the pixel format, it does not include a palette for indexed pixel types.
SDL_PixelFormatEnum has been renamed SDL_PixelFormat and is used instead of Uint32 for API functions that refer to pixel format by enumerated value.
SDL_MapRGB(), SDL_MapRGBA(), SDL_GetRGB(), and SDL_GetRGBA() take an optional palette parameter for indexed color lookups.

Improve the bucket distribution of SDL_HashTable

SDL_HashID does no hashing, which isn't good if the lower bits of the key aren't evenly distributed.

wayland: Only set the window geometry when viewports are unsupported
...
Setting the window geometry on the xdg-toplevel path is a hack used to prevent protocol violations if a buffer with an old size is committed. Since viewports decouple the window geometry from the buffer size, this is not needed if viewports are supported.
Fixes an invalid window geometry warning and incorrect window overview size for fullscreen windows in GNOME.
