...however, from an efficiency standpoint, using multiple clip rects
is almost certainly better, because it ensures that the characters are
only painted once. This is slightly more complex in TextInput and
TextArea, since the selection may bisect the text, resulting in up to
three clip rects. However, this is a simple enough problem to solve
and is probably worth doing (especially in TextArea, where selections
are likely to span many characters).

FWIW, both TextInput and TextArea use the approach I suggested and I
haven't seen any odd paint behavior resulting from it.

I used 2 clip regions, but I can see that your way would be less

I'll make that change as well.
I'd keep it the way you have it now, since I've seen weird bloating
of the
glyphs happen when you paint an anti-aliased glyph over itself.
