I'm leaning to removing this bool and assignment because its name only improves readability a very tiny bit....

I think I can get rid of this...

No, I can't so I will add a comment. The issue is that (and maybe this is a bug) hit testing the bottom of the line is considered the top of the next line (i.e. there's no gap in the programming model, though visually there could be via CSS line-height). So, a height of glyphWidth (because this is Ahem so things are square) or greater will cause the hit test to hit the next line. I don't want that because it then triggers another behavior: hit testing below the last line (also above the first line I think) is as if the entire line was hit (this is to cause a selection highlight of the entire line when painted). So, I just need to pick a height < glyphWidth. I like small things, so I chose 1.

This is not needed.
