Modern shader-based OpenGL no longer has transform stacks: we need to
implement GPU transforms ourselves. This is all handled by VisPy, and we
have total control on that architecture. We do want to support 2D and 3D
simultaneously. We are still in the process of designing this architecture
though, and I guess it would certainly make sense for matplotlib devs to be
involved in the discussions...
