DirectFB/SDL backends

[Eric Maland]

Hi,

I see in some of the list archives reference to previous work on a  
GNUstep DirectFB backend.  I have considered working on something  
like this and was wondering if anyone had either prior work to share  
or input on why it's a good or bad idea.

I've also considered building the backend on SDL, which has  
accelerated hardware support via DirectFB.  Building it on SDL may  
also automagically add support on other platforms in some form.  Is  
this a totally misguided idea or am I correct in thinking SDL could  
be a usable backend?

Also, is there any documentation on the backend?  I can just read the  
code, but even a really simple design doc might save me an hour or two.

Thanks!
Eric
