underline support about fonts HOT 4 CLOSED

Any idea how this works? I think I saw something about underline thickness in the metrics spec but I'm assuming we create the control points ourselves?

nope... might even be more of an IS.Drawing/renderer level thing where we just need capture and pass-a-long enough metadata about the glyphs to extrapolate the correct underline location across each line.

So things like triggering line start/end callbacks (with some line level metadata possibly, a rect being the most likely item)
Making sure we expose underline widths (based on fontsize), and the underline anchor points etc (might just be a case or returning exactly where the baseline is)

Ok.... I'll start investigating what we should capture from the font metrics at least and go from there. I might have a look at how Avalonia handle it.

Fixed with #251
