Jumping right in

To get myself familiar with how a Gallium3D front-end works I downloaded the source to Mesa and built the library. I had a little trouble trying to figure out which make target built Mesa using SoftPipe, but someone on #dri-devel was kind enough to tell me. I also downloaded openChrome's libXvMC source, but it's not immediately clear to me how the library works. It appears to do some work in terms of Xlib, xext, and others, but expects a few functions (the ones that actually touch the hardware) to be provided and linked in. Odds are this is where the Gallium3D calls will end up.
