ANNOUNCE: gstoraster 1.03

[Helge Blischke]

Ghostscript 9.xx does all color rendering via ICC profiles. 
Unfortunately, the ICC profile that is used to handle the /DeviceCMYK color 
space does not preserve pure black (i. e. CMYK values like [0 0 0 k]) but 
instead renders at least part of the black component as a combination of 
cyan, magenta, and yellow.
This not only contradicts the usual semantics of a device color space but 
leads e. g. to dithered gray output on blackand white devices like label 
printers.
The now updated version of the gstoraster filter works around this bug (or 
is it a feature?) by replacing such black-only CMYK colors by the equivalent 
gray value.
