Use double-click as the activation event for transition presets. Also fixed the bug when applying a style preset before the transition preset, which disabled transitions after the first one. commit f3207f39ea9d8c1c34246217a23d3a689671903d Author: Nivesh Rajbhandari Date: Fri Mar 2 11:21:29 2012 -0800 Don't draw transform handles if the stage is the target element.
