#4095 closed defect (fixed)

Polygon hatch problem for angles 90-180 and 270-360

Description

After #3847 (global origin for polygon patterns) was fixed in r12807, polygon hatches do not render correctly for angles between 90 and 180 and 270 and 360 (and 0 to minus 90, ...). I attach some illustrations.

fixed in r12816, my bad I hadn't retested >90 angles after adding a small 1.0/sin() optimization.

Seems to work now. No performance problems. Great!
