	* app/tools/gimpmagnifytool.[ch]: lots of fixes and changes:

	- Request click events and use them instead of looking at the
	  distance the mouse travelled ourselves.
	- Also zoom when the user draws a very thin rectangle or just a
	  line, there is no reason to treat that as click.
	- Changed all calculations and stored values to double so the tool
	  continues to work smoothly at high zoom levels.
	- Fix scale calculation when zooming out (was totally b0rk).
	- Changed offset calculation when zooming out so that the current
	  viewport ends up within the drawn rectangle (which is the
	  opposite of what zooming in does).
