[GnomeMeeting-devel-list] Superimposing graphics over remote image

[Dan Sandberg <x cs stanford edu>]

Hi,

I'd like to super-impose graphics over the image of the remote user. 
Can someone give me a quick hint about which file I should look into for
this kind of thing?  [ Where is the frame buffer that holds the remote
image? ]

Thanks!
