The current grid visualization relies on drawing an additional wireframe representation. This has two problems:
1) Grid size changes imply recomputing all bezier elements and intermediates (in most cases).
2) Fine-grane grids require an increase of the number of primitives
A solution to this problem would be to have a synthetic texture (every fragement chooses its own color based on equations and the u,v position of the fragment).
