[Openicc] cups-filters

[Joseph Simon]

Hello Till,

Color management in the filters is now housed in the new
cupsfilters/colormanager code. This should make it easy for future updates,
as the color management code in the module is shared throughout the
appropriate rasters (with the slight exception of foomatic-rip).

The "cm-calibration" CUPS bool option - which disables color management
throughout cups-filters - should be ready for use as well.

Right now, it is no longer a requirement that the color space be the same
between the two - I have recently added code in rastertopdf to handle 8-bit
color space conversion that will output a properly formatted PDF. So in the
case of embedding a profile, using a CMYK profile would convert the raster
image to a PDF with a CMYK color space.

I would need to add code in cupsfilters/image-colorspace to handle the
16-bit conversion.
