Support SGR 9 for strikethrough effect on text.

Browse Source 
This is mostly easy: it's just like drawing an underline, except that
you put it at a different height in the character cell. The only
question is _where_ in the character cell.

Pango, and Windows GetOutlineTextMetrics, will tell you exactly where
the font wants to have it. Following xterm, I fall back to 3/8 of the
font's ascent (above the baseline) if either of those is unavailable.
