because it is very fast. If a glyph is missing, I use
CTFontCreateForString() to pick a better font, and that usually works.

of which draw their own backgrounds. The code for the custom d

YES for all rows, which is what I wanted.
So, err what is 1) for? It's a property, it exists, it's in the documentation
but it doesn't seem to do anything.
