fbdev graphics subsystem

I have started to write a graphics subsystem for fbdev the linux kernel framebuffer.
So far I got:

* Bitmap abstraction
* Object oriented using ObjC
* Automatic expose handling
* Display server with client lib communicating over UNIX sockets
* PNG loading with libpng
* Font rendering with Freetype
* .. and some more stuff..
And of course a couple of screenies, stay tuned for videos showing animation and stuff :)
