exploiting the new interface in vnc.c (Stefano Stabellini) 

This patch exploits the new DisplaySurface and PixelFormat structures in
vnc, making the code easier to read allowing further improvements.

Compared to the last version I fixed a bug that prevented the hextile
encoding from working properly.
