-- ChangeFont should have an extra arg, to allow for not resizing

- call ChangeFont so we can pass FALSE if the size has been passed
- as the default (which means: wxWin should choose an appropriate
- size, so Motif should expand/contract the widget as appropriate).

-- Colour setting in widgets (almost done).
