* Cubemark, a microbenchmark which renders a very large number of

|
* very simple objects. This stresses the throughput of the SVGA3D
|
|
* command pipeline and API layers.
|
|
*
|
|
* Half of the cubes are rendered using fixed-function, and half of
|
|
* them are rendered using shaders. This helps hilight any performance
|
|
* differences between per-draw setup for FFP vs. for shaders.
