7d034dcfb1 Exported the software renderer texture functions to make easier to create 
a renderer based on a framebuffer.

Fixed an initialization bug with the dummy video display mode.

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.

d1be2d9e1c Solved the performance problems by introducing the concept of a single-buffered 
display, which is a fast path used for the whole-surface SDL 1.2 API.
Solved the flicker problems by implementing a backbuffer in the GDI renderer.

Unfortunately, now using the GDI renderer with a backbuffer and HBITMAPs is
significantly slower than SDL's surface code.  *sigh*
