mouse-drag-and-drop-region cancels the drag and drop operation once the
mouse pointer moves back into a frame that was created by the current
Emacs session, so that more detailed mouse tracking can be used.

Without that, mouse-drag-and-drop-region is noticably degraded.

We aren't rejecting alternative GUI environments (in fact we are almost
certainly the only program supporting as many as we do), just not making
them the default.  Not when over 90% of Firefox users (which covers the
GNU/Linux demographic quite well) are still using X Windows.
