24-bit color support to Xvnc

[paresh masani]

Could you please give the answer to following question then i think i will
be all set for colors/depth.

What is the "Server default" and "Pixel Format"  and why "PixelFormate" is
stays at depth 24(rgb888) eventhough I have created session using "vncserver
-depth 32"? Please refer the attached images for reference.

Thanks,
Paresh
