Seeking adive, comment, warnings, etc on a new backend

[cehardin]

I'd like to make a new backend for gnustep which uses DirectFB.

My plan is to use win32 and winlib as a template, since they seem more 
straightforward than X11 and xlib.  Is this is a good idea?

Before I venture off into this creation does anyone have any tips, 
warnings, comments?  i don't like rushing into something and end up 
doing it wrong.  I have been reading the source code in gnustep-back 
and have learned quite a bit already.  But it's always a good idea to 
ask for advice.

BTW, DirectFB is a bit different than X11.  For one, there is no such 
thing as a "window server".  the apps cooperate with each other through 
the use of a kernel module called fusion to draw to the screen and 
receive input.  Second, there is no concept of a window manager.  This 
would mean that the window decoration and management code would have to 
be in the back-end, is that even feasible at this point in time?

Thanks for the help,

Chad
