+ * 11/26/03 David Suffield (gdevijs-krgb-1.0.patch)
+ * (c) 2003-2004 Copyright Hewlett-Packard Development Company, LP
+ *
+ * 1. Removed hpijs 1.0-1.0.2 workarounds, use hpijs 1.0.3 or higher.
+ * 2. Added krgb support.
+ *
+ * 02/21/05 David Suffield (gdevijs-krgb-1.1.patch)
+ * 1. Fixed segfault issue with 1-bit color space.
+ * 2. Fixed z-order issue with colored text on black rectangle.
+ *
+ * 02/22/06 David Suffield (gdevijs-krgb-1.2.patch)
+ * 1. Fixed krgb buffer overflow issue with out-of-band data in fill_rectangle and copy_mono.
+ * This buffer overflow condition occurred with fullbleed print jobs that had k-band images.
+ * 2. Added Dan Coby (artifex) fix for gsijs_read_string_malloc gs_free *str memory leak.
+ *
+ * 06/02/06 David Suffield (gdevijs-krgb-1.3.patch)
+ * 1. Revisited the krgb buffer overflow issue with out-of-band data in fill_rectangle and
+ * copy_mono. Changed the fill_rectangle and copy_mono to an inner loop buffer check
+ * instead of a outer loop x/y extent check.
+ * 2. As requested by Ralph Giles, added K 1-bit and 8-bit support for krgb, but only 1-bit is
+ * implemented for now.
+ *
+ * KRGB definition:
+ * 1. K=1-bit or 8-bit black plane, RGB=24 bit color raster.
+ * 2. K-plane will only contain objects that are black text and black line drawings.
+ * 3. RGB raster will not contain K-plane objects.
+ * 4. K resolution and RGB resolution will be equal.
+ * 5. K-plane will be byte aligned.
+ * 6. K-plane 1-bit definition; 1=black, 0=nothing (KRGB).
+ * 7. K-plane 8-bit definition; 255=black, 0=nothing (KxRGB).
