Labels for some reason seem to be more forgiving, but when you increase
font size enough, they get messed up too (see test1.pd for an example).
The problem is more apparent when using number2 object. See attached
test2.pd patch--there should be no scrollbars since the object fits, yet
there they are nonetheless. If you make the font size bigger, it gets
worse.
