I have made a first attempt at modifying Xv to support writing to 
pixmaps. While I can see the Intel driver is receiving a pixmap drawable 
and apparently writing to it, I see nothing on the screen. The following 
is a list of the files that have been modified:

Xorg (1.3.0)
hw/xfree86/common/xf86xvpriv.h
hw/xfree86/common/xf86xv.c

Intel (2.4.1)
i830_video.c

What is the best way for others to review these changes, and offer 
suggestions?

Many thanks
