New Revision: 8122

Modified:
   trunk/gs/src/gxfill.c
Log:
Banding : Extend clist language with trapezoids, linear color trapezoids and linear color triangles (continued 2).

DETAILS :

This fixes Comment #4 of Bug 689344 "Regression: cmyk output broken with banding".

The revision 8020 of gxfill.h doesn't account a case of pcpath==NULL
in gx_default_fill_path.
However the clist reader does such calls with halftoned colors.

EXPECTED DIFFERENCES :

Fixes resent regressions (a halftone color dissipation) with pkmraw -r300 -K1000000 -dMaxBitmap=10000 :
