New Revision: 8527

Modified:
   trunk/gs/src/gxht.c
Log:
Fix for regressions introduced with rev 8526. Some resolutions of CMYK, 1-bit
per component devices that had CMYK colors and Gray colors had strange dithers.
Bug 689706.

DETAILS:

The previous changes missed changing the cache index logic in gx_render_ht_1_level,
If the cache had been set with one of the other routines, gx_render_ht_default or
gx_dc_ht_binary_load_cache, then gx_render_ht_1_level would be inconsistent.

EXPECTED DIFFERNCES:

This is expected to resolve the regressions from rev 8527 with pkmraw on:
