A calibration mode that is invokable from upstream for the purposes of a specific type
of calibration (ie. calibration curves) should be a mode that is appropriate for that
purpose. It doesn't necessarily map to wide open and raw. It shouldn't do total ink
limiting, but (for inkjet technology) it needs to do per channel gross limiting, to
account for the dot overlap of the printing mode.

ie. the aim here is really to have the appropriate print path modes to support
the smooth and reliable operation of certain specialised applications, namely
calibration and profiling.

(See <http://lists.freedesktop.org/archives/openicc/2011q2/003659.html> for a summary
 of the four modes. We are now talking about just the last 3 modes.)
