Speed up the fixed count parametric/radial sort
The fixed count stroke shader was executing a sort loop long enough to
handle 1024 parametric segments, when in reality it will never see
more than 48. This CL cuts the per-vertex sorting work nearly in half
by reducing the number of iterations from 10 to 6. (The indirect
tessellator continues to use 10 iterations.)
