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.
