Subject: [PATCH] Use the surface palette directly for the texture in
 SDL_CreateTextureFromSurface()

This is a better fix for https://github.com/libsdl-org/SDL/issues/16227. It also allows you to create a whole set of indexed textures from surfaces that share a single palette and then modify that palette to change all textures.
