[gui] [PATCH] FYI: Dispatching MouseMotionEvents

- Subject: [gui] [PATCH] FYI: Dispatching MouseMotionEvents
- Organization:
Hello,
I committed the following patch to the java-gui-branch. It enables
MouseMotionEvents for both heavyweight and lightweight components. All
of the groundwork was already there; I just needed to enable two event
types: MOUSE_MOVED and MOUSE_DRAGGED. I also had to fix event enabling
for lightweight dispatchers to make this work properly.
