Having more trouble than expected trying to accomplish some feedback when a
scene is being zoomed. Specifically, I have reason to want to know the
distance of the camera from the scene.center throughout the zoom.
But I am finding that the mouse events that would allow me to accomplish
this easily only apply to the left mouse events.
I can identify a "middle" press, but if I do a
while scene.mouse.press == 'middle':
<get me the distance>
I can't find a way to get an event that will turn it off. Same with
scene.mouse.button.
Anyone have ideas?
