Yes.  Unfortunately this is a hard thing to fix -- basicially we would need
to draw a circle right on the front clipping plane that would mask each
sphere that intersects the front clipping plane.

Mixing apples & oranges.  Plugins only work with Tcl/Tk-based versions of
PyMOL, such as the pure X11 and Hybrid X11 builds.  MacPyMOL is written in
Cocoa, not Tcl/Tk.
