Hello Tim (is that the right name to address you by?),

I'm afraid that no one has a lot of time to help you with this.  I will
make a quick suggestion about where you could start looking.  You will
probably have most luck studying the code and asking precise questions
when things are not clear.

You will probably want to start by looking at the X11 libGL.so and its
dependencies.  This is a purely user-space library which marshalls the
OpenGL command stream and some information from GLX commands and sends
it to the host, currently via the "guest" device, on Windows through the
graphics device.  On the host the 3D content is rendered to a host
window - a separate one from the normal guest screen window, which
sometimes causes unwanted artefacts when 2D and 3D guest rendering are
mixed.

It will probably take you a while to get used to our build system to
work out what goes into libGL.so (including generated files), but you
will probably have to go through that.

Hope that helps for a start.

Regards
Michael
