Date: Thu, 04 Sep 2003 02:12:35 +0200 From: Ignacio Casta�o <castanyo@yahoo.es> Subject: [SDL] SDL_GL_GetAttribute( SDL_GL_MULTISAMPLESAMPLES ... It would be nice to add the following lines: case SDL_GL_MULTISAMPLEBUFFERS: *value = 0; break; case SDL_GL_MULTISAMPLESAMPLES: *value = 1; break; in wincommon\SDL_wingl.c int the function WIN_GL_GetAttribute at line 484, so that it returns the correct values when arb_pixel_format is not supported.
