Implement the basis of the Maxwell 3D engine together with a macro
interpreter. The Maxwell 3D engine handles all 3D rendering, currently only non rendering related methods are implemented. Macros are small pieces of code that run on the GPU and allow methods to be quickly called for things like instanced drawing.
