Gadget Menu: Cancel menu after a drag *EITHER* vertically or horizontally, not *BOTH*. Fixes longpress menu interrupting drag in gadgets such as pager.

The longpress menu was only getting cancelled if a drag occured at a
distance of least 25 pixels.  This is due to the code checking for horizontal drag
distance + vertical drag distance >= 25.  I believe the intent here was
to cancel drag if >= 5 vertically or >= 5 horizontally, not both.  Most
drags wouldn't be 25 pixels in a single gadget such as pager, and a 25
pixel drag would not happen quick enough to offset longpress.  This
commit also lowers the drag cancelling threshold to 3 pixels, not 5.
