Fixed bug #421 Comment #3 From esigra@gmail.com 2008-04-09 11:46:46 (-) [reply] ------- This bug also needs to be fixed for SDL_GetRGB and SDL_GetRGBA (those should not change the format of the surface either). Until this is fixed, I still need to const_cast the format parameter in calls to those functions.
