Emphasized the separation between SDL_Surface and SDL_Texture - SDL_Surface is a system memory representation of pixel data - SDL_Texture is a video memory representation of pixel data The concept of SDL_Surface with SDL_HWSURFACE is no longer used. Separated SDL_Texture types by usage rather than memory type - SDL_TEXTUREACCESS_STATIC is for rarely changed pixel data, can be placed in video memory. - SDL_TEXTUREACCESS_STREAMING is for frequently changing pixel data, usually placed in system memory or AGP memory. Optimized the SDL_compat usage of the OpenGL renderer by only using one copy of the framebuffer instead of two.
