After transforming some coordinate values to screen pixel positions I thought to do the reverse, taking a pixel position back to original values. Is there an untransform hiding in the code?, like ($x,$y) = $aff->untransform($x,y) I suppose an ->invert() or something could invert the whole transform object. So maybe $rev=$aff->clone->invert to get a reverse. Though I think I only want a handful of untransforms. Incidentally, as a suggestion for the docs, I like seeing a sample call for methods rather than a description in words (or a sample as well as words). I find a sample easier to read quickly, cut and paste, etc.
