I'm dragging (and releasing) an object around a canvas via
startDrag and stopDrag.
However, if while dragging I drag outside the browser window
and release the mouse button, I don't get a mouse up, and so I
don't call stopDrag. When the mouse moves back over the browser,
the object is now stuck to my mouse.
Is there a recommended way to handle this situation? I
basically want to get a mouse up even when the mouse up happens
outside the browser.
