hard coded font sizes

[jacob berkman <jacob ximian com>]

in the fix for bug #78001, it uses hard coded font sizes.

for a11y reasons, this is frowned upon, right?  and we should be using
<span size="foo"> markup strings to do size changes?

or is there a way of saying "give me this font, but bigger" to pango?
