Everything ought to get bigger in such circumstances, as the size of a GL 
unit remains the same. Supposing a default camera/viewport, for an XY 
object at depth Z=0, the image rows go from +4 GL units to -4 GL units, 
and the image columns go from -4*aspect GL units to +4*aspect GL units.

aspect is the image width divided by the image height.

If you just want to make a bigger sheet, you need to increase the number 
of vertical units from 8 to something proportionally bigger (new window 
size divided by old window size, times 8).
