Recommend replacing RasterizeGLContext withRasterizeCudaContext

[Assassin-plus]

Since the nvdiffast developr mentioned in sicxu/Deep3DFaceRecon_pytorch#108

Also, the current version of nvdiffrast includes a Cuda-based rasterizer that doesn't require OpenGL. You may want to consider switching to that by default, as setting up OpenGL can be tricky on some platforms.

I recommend to replace the RasterizeGLContext() function in core/NvDiffRastRenderer.py line 25 to RasterizeCudaContext().

It should be fine since I can run the code after the replacement, and if I don't replace it, I came up with the same problem in sicxu/Deep3DFaceRecon_pytorch#2

$ python experiments/smpl/optim.py

Thanks! I'll check it.
