Produce fitted images

[grislis]

Need to loop through all dimensions except lifetime. Perhaps fitting could be an op or an algorithm or some other IJ2 concept. Want to support a 'chunky pixel effect' as currently supported: fitting occurs coarsely at first, skipping every n pixels and drawing fat n x n pixels, gradually being refined until every pixel is fitted.

Fitted images are starting to work, but not complete as in IJ1 version.

Missing is the use of a lifetime LUT, automatic adjustment of ranges, manual adjustment of ranges through a histogram tool, hiding of out-of-range pixels with the histogram tool.
