No, they aren't. They are certainly not black-and-white: they use
faces.

Drawn how? Bitmaps are images, and drawing images in the text area
means we need to invoke all the machinery of redrawing a certain
screen line, be it on the mode line or elsewhere. That's how Emacs
draws stuff; we don't have any way of directly poking the glass with
an arbitrary bunch of pixels, at least not one that I know of.
