6b348f07c7 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.

From: "Philippe Plantier (ayin)"
Subject: [SDL] Problems allocating large surfaces

There are problems when allocating large surfaces using SDL_CreateRGBSurface.

When, for example, we try to allocate a surface wider than 16384 pixels,
the calculation of the pitch overflows; this leads to a surface that
has the w and h flags correctly set, but whose "pixels" buffer is too
small. That may lead to heap corruption.
