Fixing the most obvious "bugs" (=missing functionality) now.

Aha, there is no coordinate system for the bounding rectangle of the 3D?
Do we need it?

This looks like a bug:
 	set arrow 1 from graph 0,0,0 to graph 1,1,1
 	splot x*y
 	pause -1
 	set view map
 	replot
 	pause -1
 	plot x

I would expect a line in another diagonal.

You mean 'set margins'? I think this is the most easy and helpful fix. This 
would allow to scale down the 3D plot area manually in order to allow enough 
space for the color box when needed.
