I don't think it will be acceptable to write a "similar" layer. The
PDF text layer will have to identical to what you see on screen. Tiny
differences might be acceptable but you definitely want to apply the
same font mapping, glyph substitution, line-breaking and bidi
algorithms as the text tool. That's why you won't get around using
Pango for the text layout.

I was talking about a third-party Pango extension. It's not part of
the standard Pango package.

I don't see how this would avoid UI cluttering. You don't expect
people who want to use an effect like Grain Merge to enter the
mathematical formula manually, do you?

(2) would be plug-in only as well, no?
