This would be *possible* (with libosmesa), but the obvious problem is we could 
end up using openGL features that don't render properly on everyone's driver 
anyway (despite openGL being a standard, etc., implementations are buggy, 
c.f. standards like ACPI, etc.)  I'm not against it in principle, just want 
to point out the bugs that can happen with it.
