Alt-click is shadowed in GNOME

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use GNOME
2. Run TopMod
3. Try rotating the view by alt-clicking

Alt-click is normally taken by GNOME and others for moving a window, so 
alt-drag just moves the topmod window instead of rotating the view.

I changed it to start rotating the view when alt was pressed (mouse button not 
required) and it was quite usable. That's a suggestion, but it might not be 
best for everybody.
