check against the c example:
- document missing APIs not yet available in skia-python (e.g. the GL routines and GL enums,
GR_GL_GetIntegerv(interface.get(), GR_GL_FRAMEBUFFER_BINDING, Matrix.mapPoints/mapPoint, SurfaceProps(), ) as of m126
- check line-by-line agreement with the C++ example (somewhere changed in the middle to try out and forgotten to change back)
- document pythonic changes deviated from the c++ example (e.g. not using Skia's random number nor TArray template class)
