Mouse interaction doesn't really have much to do with this --- or 
rather, it shouldn't.

The key problem are the third and fourth parameter to 'set view', and 
how they affect the plot.  From the start these parameters were the 
wrong approach to the perceived problem of incomplete space utilization 
by 3D plots.  They cause the plot to outside all sensible boundaries --- 
the graph box, the viewport, and eventually even the page itself.

surface_zscale (the fourth argument of 'set view') is the worst of them. 
  The only effect this parameter reliably has is to blow the plot off 
the page.

I think both of these variables should be killed for good.
