That's interesting. When I try to set the grid from the menu, it tells
me "must be a Point with coordinates between 1 and 36".
When I look at why the 36 in setGridSpec, the comment says "because it
was that way before".
However, 80 at 80 works.
Hmm... this is because of gridFormOrigin:grid:background:line:
40 roundTo: <grid x>
because the assumption was that you'd never want anything bigger than
40 pixels (or 80?) on a side.
40 roundTo: 79 => 79
40 roundTo: 80 => 80
40 roundTo: 81 => 0
40 roundTo: 85 => 0
If you redefine Number>>roundTo: to be
^self < quantum
ifTrue: [ quantum ]
ifFalse: [ (self / quantum) rounded * quantum ]
Though that's probably a questionable fix.
