[GRASS-dev] d.vect render=l clipping weirdness

[Hamish]

Hi,

regarding "d.vect render=l", I have noticed some weirdness and done some
comparitive eyeball tests on the output:

  http://bambi.otago.ac.nz/hamish/grass/bugs/d.vect/

Conclusions:

 * polylines (l,d,r) are not crisp
 * clipping is wanted in a xmon with white-band out-of-region edge areas
 * "l" clipping (culling) leaves mixed out-of-region artifacts
 * "c" is off-by-one pixel at edges
