A picture remembers whether its pivot was placed by hand: a hand-placed
pivot is saved and kept through a resize, a default one is not saved
and recentres after a resize. Two actions changed that flag outside
their undo step:
- applyCrop() marked the pivot as default after moving it to the centre
of the kept region. After Ctrl+Z the pivot was back where the user
had put it, but marked as default, so the next save dropped it.
- dragging the pivot handle marked it as hand-placed. After Ctrl+Z the
pivot was back at the centre but still marked as hand-placed, so a
later resize left it at the handle's anchor corner.
pivotIsCustom becomes a property, and both actions put it into their
undo command next to rawPivot. tst_imagecropundo checks that a project
saved after undoing a crop keeps its hand-placed pivot.
