From: Couriersud
Subject: SDL1.3 DirectFB patches

The attached contains the following directfb changes:

- Dynamic loading of libdirectfb.so. This may to turned off as well in configure
- Use linux-input by default. May be switched off by environment variable.
- Added some code which will use directfb's x11 backend when DISPLAY is set.

To disable to use x11 backend when DISPLAY variable is found use

export SDL_DIRECTFB_X11_CHECK=0

To disable the use of linux input devices, i.e. multimice/multikeyboard support,
use

export SDL_DIRECTFB_LINUX_INPUT=0

To use hardware accelerated YUV-overlays for YUV-textures, use:

export SDL_DIRECTFB_YUV_DIRECT=1
