To Mike Mueller: I'm not competent to comment on the wxPython question you
ask; perhaps someone else will comment.

Concerning mouse control of the scene, there are two things to say. I just
learned that the display object (which governs overall behavior of the
window, such as its height and title) has attributes userzoom and userspin.
These are normally set to 1 (true), but you can turn off the capability:

	somedisplay.userzoom = 0  # user cannot zoom in or out of the scene
	somedisplay.userspin = 0     # user cannot rotate the scene

You can write a program which detects mouse clicks and toggles these
features.

Dave Scherer has proposed a change to the default behavior: Left button
would not zoom unless you hold down some key (such as control), so that
left button down would be used for dragging. This would be more intuitive.
I have seen new users be confused about dragging with the mouse buttons up.
We don't expect to make this change immediately, but it is on the list.
