You'd also need to call XFillRectangle(...), otherwise the ellipsis will
*overlap* what was previously there instead of *overwriting* it.

And on the topic of ellipsis_width, we currently don't account for
fallback font:

        usedfont = drw->fonts;
        drw_font_getexts(usedfont, "...", 3, &ellipsis_width, NULL);

The assumption here was that every font should have '.' but if that
turns out to be wrong, then the font width will be incorrect.

I don't think we can call drw_fontset_getwidth() though, since that'll
recurse back into drw_text().
