I think a feature to make Emacs capture a screenshot of itself would be very
nice (and hey, in the future, it could even be SVG instead pixel-based! That
would be wonderful).
And yet I'm not sure whether adding a flag to capture a screenshot after each
redisplay cycle is the way to go. People often surprise me with the stuff they
come up with Emacs, so adding a general post-redisplay-hook may enable plenty
of things that we're not thinking about (and at worst, people won't use it
much, just like the currently existing pre-redisplay-function).
Plus, it's not obvious that we could stretch such a capture-after-redisplay
flag to cover all screencasting use cases. For example, since capturing and
saving a screenshot takes time, we'd probably want to let Lisp code decide for
each redisplay cycle whether to take a screenshot or not; it could decide this
based on time elapsed since the last screenshot, or other factors.
What do you think?
