This turns out not to quite work. David's program does
calculate (nicely) the plot size to deal with funny-shaped windows,
but doesn't deal with oddly-shaped arrays going into surface.
For example,

figt=dist(60,10)
window,0,xs=500,ys=500
surface,figt,/lego,pos=aspect(1.0)

certainly doesn't produce square lego pixels.

Any alternative suggestions? This is vexing...If IDL 5 has a
/iso keyword I'd even be willing to start installing the beta.

(Please email as well as post replies - my newsfeed is unreliable.)
