Otherwise, scrolling in a document with stretch glyphs can cause them to
overwrite parts of the mode line, in some cases.

I asked Po Lu to move the focus call out of ns_dumpglyphs_stretch and
into ns_draw_glyph_string as it's the only caller (in two places) and
it meant we didn't have to handle nested ns_focus calls further down.
I forgot to check this call had been fixed in subsequent patch sets.
So yeah, it's good.
