A number of video backends need to get ARGB8888 formatted surfaces with premultiplied alpha, typically for mouse cursors. Add a new function to do this, based loosely on legacy_alpha_premultiply_ARGB8888() from the KMSDRM backend. The new function, SDL_PremultiplySurfaceAlphaToARGB8888() takes two arguments: - src: an SDL_Surface to be converted. - dst: a buffer which is filled with premultiplied ARGB8888 data of the same size as the surface (assuming pitch = w). This is not heavily optimised: it just repeatedly calls SDL_GetRGBA() to do the conversion, but should do for now. |
