* example, if you have a geometry with triangle strips, fans, and triangles, it will
* combines them into one a minimal number of primitive sets containing GL_TRIANGLES.
*
* Limitations:
*
* - Will not operate on geometry with vertex attributes.
*
* - For geometries with tex coord arrays, all geometries must have the same configuration
* (i.e., number of texcoord arrays, and the same unit bindings).
