Update TrackPanel cursor for unmoving mouse, changing display...

Browse Source 
... This fix might not be exhaust the possibilities.  Some examples covered:

When an undo state is pushed.  For instance:  Hover over bottom of sole track
for resize cursor, then Shift+C to delete it.  (Cursor change used to happen
at Shift key up, now sooner.  Maybe your shortcut does not include Shift.)

When an undo state is modified without a push.  For instance:  hover over right
edge of selection.  Hit Shift+Ctrl+A to remove the selection.  (Again, change
cursor before keys up, and even if no modifiers in the shortcut.)

When scrollbars change for any reason, such as pinned play or Shift+scrollwheel.
(Clip boundaries may pass your mouse.  Cursor change and also snap lines come
and go.)
