Size is a naughty beast in Swing. There are multiple variants of it:
actual, minimum, maximum, and preferred size, and how they work, if
they work at all, is determined by the layout manager. For MigLayout,
the default used by Snow, the easiest option is to forget about the
size properties altogether and use layout constraints, in your case:

(scroll (:layout "w 100, h 100") ...)

or width/height instead of w/h if you prefer longer names.
