rotatexyz msg doesn't update mouse control in handle

Hi cycling,

Where the rotate message in handle also updates the mouse control rotation, rotatexyz doesn't. The patch below illustrates this. Is this to prevent users from running into gimbal lock?

We solved the problem by stupidly feeding the handle's rotate arguments back into the handle as you can see in the example. Could this lead to gimbal lock somehow?
