Why can stretch glyphs only be added between words?  Is it because we
ask the font backend to draw a series of glyphs in one go?

If that's the case, perhaps we could stop doing that if we're doing a
gridded display?

One other thing that occurred to me (but I didn't look at closely) is
whether it would be feasible to work on the glyph matrix for a line
after it's been composed.  I remember you doing some work on that when
we talked about "compressing the mode line" -- I think you basically
went over the matrix and removed some of the space glyphs?  (That
approach didn't work for other reasons, but the basic post processing
thing did work, I think?)

Do we have enough info about the glyphs at that stage that we could add
some stretch glyphs to gridify the line?
