[argyllcms] Feature request - fill-in with white patches - or - query number of patches that will fit on a page

Hi,

With my linearization experiments, I've found one problem with Argyll's targen and printtarg utilities.

Because the targets I'm generating here are for linearization, they contain *only* single channel steps (targen -f0 -m0 -snn) and the ink limit at this early stage is set for an expected maximum 100% coverage.

The problem is this: If when generating the actual printable target the number of patches doesn't perfectly divide into the number of columns on the page, Argyll makes up the number of patches with a few combination patches, causing paper saturation. Is there any chance of a switch to either turn this off, or make it use extra white patches instead?

Alternatively - or perhaps a better solution, since it would have other uses - is there any chance of a way of querying printtarg to ask it how many patches will fit on a sheet of a specified size, targetting a specified instrument? With that information I could simply request extra white patches so there are none spare for Argyll to fill in, and sidestep my issue altogether.

It would also allow me to choose a sensible default number of patches in my linearization tool.

All the best,
