Identify the Bug or Feature request

Fixes #5032

Description of the Change

The issue was caused by the combination of DefaultTool keeping around previous drag positions, and the surprising ability for mouseDragged() events to start before corresponding mousePressed() events if other mouse buttons are already presssed. This PR fixes the problem by clearing drag state whenever a drag completes, and double-checking that a map drag has actually begun when in mouseDragged().

Possible Drawbacks

None

Documentation Notes

N/A

Release Notes

  • Fixed a bug where the map can jump wildly if starting to drag it with other mouse buttons pressed.

When a drag is completed, the drag state is completely cleared so it can't be reused again later, even
accidentally. This ensures that we aren't affected by the strange case of a right-button drag event comming in before
the right-button press event.
