Subject: Directfb driver for SDL1.3

Hi,

the attachment contains a patch for a SDL1.3 directfb driver. It supports:

- Renderer "directfb":

Hardware acceleration as supported by the underlying directfb driver. With a
radeon X850, testsprite2 runs at 50% to 70% of OpenGL (X11, dri) performance.

Also supports hardware accelerated yuv overlays. This must be enabled by sett
ing:

export SDL_DIRECTFB_YUV_DIRECT=1

- Renderer "opengl"

Supports software opengl using mesa opengl (make linux-directfb).

Some more information may be found in README.DirectFB

There will certainly still be some bugs, and there is some debug code around.
 When I find some time, I will compile against directfb-0.9.25 as distributed
 with ubuntu 7.04.

The diff also contains a fix for SDL_LockYUVOverlay fixing a bug in  *pixels
and pitches initialization.

Kind regards,

couriersud

      Emphasized the separation between SDL_Surface and SDL_Texture · 6b348f07
      Sam Lantinga authored 
       - 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.
