- replaceImage(), mirror() and setTransparentColor() no longer add a
dummy QUndoCommand child: the imageSource child already keeps
QPropertyUndoCommand::mergeWith() from merging two of them.
- The explanation of the position and pivot maths moves from crop() to
applyCrop(), where that code now lives; the stale older doc block of
crop() goes.
- applyCrop() returns false when nothing was cropped, and
qet.cropImage() passes that on. tst_imagecropundo checks it for the
current crop, an empty rectangle and one outside the picture.

Crop a picture as the crop tool does, in one undo step, and read its
crop rectangle back. tst_imagecropundo uses them on the real binary:
a crop that was undone is not saved, and redoing it saves it again.
