	* app/edit_selection.c: Fixed a couple of bugs with translating
	the selection mask (move tool, alt-drag):

	- Selection mask was being clipped whilst moved around, not just
	  at its final resting place.
        - Selection mask translation was being performed 'live' like the
          opaque moves even though there's simply nothing exciting to see.
	  Now the process is much faster.

	Will remove the edit_selection.c dead-code later if this change
	does not cause new trouble.
