How can I compile clanlib with sdl,directfb support?

[vncntd]

In the source code of clan2.2, I can't find the display target for sdl or directfb.

ClanLib SDL support was removed for ClanLib 2.1

(This is about SDL 1.2, we have not tried SDL 1.3)

The reasons were...

1) SDL's software renderer is slow compared to ClanLib's clanSWRender target. (iirc, ClanLib was twice as fast as SDL)

2) SDL was not powerful enough to use all of clanDisplay's target provider interface. (Some parts had to be emulated by our SDL extensions.)

3) Nobody used clanSDL. The targets clanGL, clanGL1 and clanSWRender contained everything everybody required.

ClanLib afaik, does not have directfb support. Again, this is because nobody required it. But we will accept patches for its support.
