Patches to add -preservecolorspace
pdftops 0.17.2 in August 2011 added an optimization to convert RGB and CMYK
bitmaps with equal components in every pixel into Gray bitmaps.
This fixes problems where PDFs with embedded RGB images would not work well
when separated into CMYK plates for printing.
There are times when it is better to leave gray images encoded as RGB as RGB.
See for example, the image

The attached patches add a -preservecolorspace to preserve gray images encoded
as RGB as RGB.</pre>
