Harley Acheson 93d226952b UI: make editor corner splitting / joining more reliable. 
* Add threshold for minimum amount of mouse movement for dragging to
  get activated.
* Limit angles at which dragging is considered an action, do nothing if
  mouse does not clearly move up/down/left/right.
* Increase action zone size vertically.
