Use SDL_Color for SDL_RenderGeometryRaw() and add SDL_RenderGeometryRawFloat()

Browse Source 
Eventually we can re-add a fast path for that data down to the individual renderers. Setting color scale would still require converting to float, and most hardware accelerated renderers prefer to consume colors as float, so this requires some thought and performance testing.
