For the one I did a couple weeks ago, I think it's fair to say that
it was safer to call the base view's Draw() first and draw my gimmick
on top, because I don't think that little graphic is very dependent
on BButton::Draw()'s implementation. If I had copied that code, then
I'd run the risk that eventually view draws would change in a way that
is visually or otherwise incompatible. I'd have an old style button
that was at best incongruous.
(The additional drawing is a green `light' that gradually fades to
black until the IMAP ping timer expires; if I want to check my
mail immediately, I press the button. So it's just a colored dot,
in a space created by starting the button label with " ". It
seems to me it would be crazy to copy BButton::Draw just for that.)
