And eventually user moving/resizing seems to work, even with aspect ratios. 

When moving/resizing, first do the operation unconstrained, then snap
(now it should be even simple to implement snapping while resizing),
then check workarea bounds and finally check constrains, while keeping
the respective fixed order for the resize operation at the same position.
Also geometry() -> initialMoveResizeGeometry, as geometry() may change
with opaque move/resize.
