  kmsdrm: Use SDL_PremultiplySurfaceAlphaToARGB8888() for cursor surface Instead of taking a direct copy of the mouse cursor surface, and then premultiplying on every BO upload (using the custom legacy_alpha_premultiply_ARGB8888 function), use the new SDL_PremultiplySurfaceAlphaToARGB8888() function, which converts a whole surface at a time, once and save the result. The already-premultiplied data is then copied from that to the BO on each upload, adjusting for the stride (which the previous implementation required to be equal to the width), thereby making the extra copy slightly useful.. This also adds support for non-SDL_PIXELFORMAT_ARGB8888 surfaces.
