[Visualpython-users] Patch for limiting zoom in vpython

[Gavrie P. <ga...@ne...>]

Hi,

I needed a feature in VPython that would let me limit the amount that
the user can zoom in with the mouse. 
After not finding a way of doing this, I have written a small patch to
enable it.
The patch adds a new attribute to "display" objects. The attribute is
named "zoom_limit", and is a float value.
In Python, you can now say: visual.scene.zoom_limit = 10.0, for example.

The patch is attached.
If others find it useful, maybe it can be added to the CVS?

Gavrie.
