This is a question of splitting global state between frames because current
tricks like ++windows_or_buffers_changed effectively prevents single-frame
redisplay optimizations. I have a few experimental patches with per-frame
fonts_changed_p and cursor_type_changed flags. Since font/cursor changes
are rare, the effect is negligible, but this opens the way towards more
interesting things. On the other side, I suspect that the most of users
are either 1) uses single-frame configuration or 2) uses reasonably modern
hardware where the complete redisplay (all frames) is faster than the period
between two keystrokes and so doesn't affect an editing experience.
