CVS commit by staikos: 

cleanups, and fix drag initiation detection.

Drag is re-enabled in non-label mode to see how the interaction is (and see if
it should be left in or reverted).  It seems to work well for me but it may or
may not be unexpected/interfere with zooming.  It is however convenient.
