 ---------------
 
 Virgil is a research project to investigate the possibility of creating a

 guest operating system to use the capabilities of the host GPU to
 accelerate 3D rendering. The plan is to have a guest GPU that is fully
 independent of the host GPU.

 implemented purely on OpenGL so you can get accelerated rendering on any
 sufficiently capable card/driver combination.
