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
