IIRC, the idea was to not trace the glyph::frame in fix_matrix because
that is not enough in the tty case because not everything is a window in
that case. That lead to fix_glyph_pool and fix_glyph_matrix in the tty
windows could be a nop because window matrices on ttys are sub-allocated
from the pools.

No, for some reason I did

  a19e818265e ; Fix last change

which removed the frame from fix_glyph_pool but left the braces which I
normally dislike if it's only a single statement.

And secondly, I don't check for window-system frames in
fix_glyph_matrix.

And my memory of that is entirely erase at the moment. How weird!

No, that's not required.
