Oh no, not again. For all postscript terminals, it's the only way to
produce large plots. And for some other terminals, it also works as scale
factor for the canvas. If you are allowed to reduce the canvas size using
'set size 0.7,0.7' you also have to be allowed to increase it by using
'set size 2.0,2.0'. And to maintain compatibility (to the old code where
no clipping was done in most terminals) we will have to handle sizes above
1, too.

Have you had a look at the new patch, #1353539? Here, correct clipping
works for postscript, png, and fig. It sets term->canvas in all terminals,
now.

Best regards
Harald
