--AppletItem::clip was introduced in order to
avoid circumstances that applets exceed their limits
and as such still events from surrounding applets.
Because of that change applets should now apply
their layout properties as valid all the time
--I have managed to solve most of the issues that were
preventing a live demonstration of applets layout
during InConfigureApplets mode... Things are more
intuitive now are updated correctly between different
layout areas... enjoy...
--container fill calculations are now tracked much
better when they are applied.
--as an improvement fill calculations are now taking place
at all edit mode states. So inConfigureApplets mode
the fill(s) applets do not throw out of screen
applets that are the layout edges
