+ at todo Read large amounts of data from Vlib into arrays, which could
+then be processed using NumPy and rendered using glDrawArrays or
+glDrawElements, so no per-line/per-vertex processing in Python. Bulk
+data processing with NumPy is much faster than iterating in Python
+(and NumPy would be an excellent candidate for acceleration via
+e.g. OpenCL or CUDA; I'm surprised it hasn't happened already).
