(gscsepr.c [1.10], gscspace.h [1.7]: 2001/04/20 +09:38:38 igorm) + - Removing the dependence of graphic library on PS interpreter. +Source Forge bug #415003. (gscsepr.c [1.11]: 2001/04/20 10:07:48 igorm) + - Optimization for shading fill. The general path filling algorithm +subdivides fill region with trapezoid or rectangle subregions and then +paints each subregion with given color. If the color is shading, each +subregion to be subdivided into areas of constant color. But with radial +shading each area is a high order polygon, being subdivided into smaller +subregions, so as total number of subregions grows huge. Faster processing +is done here by changing the order of subdivision cycles : we first +subdivide the shading into areas of constant color, then apply the general +path filling algorithm (i.e. subdivide each area into trapezoids or +rectangles), using the filling path as clip mask.
