Auto screenshots frame by frame

[Br4ssman]

For a somewhat specific need, I had thought about whether it would be possible to have an extension of the "F10" function, screenshot of the game, as a feature.

Would it be possible by means of a key combination, that the process would automatically take different screenshots for a limited time, force the same combination to stop it or simply if the game closes?

One of the few applications of this proposal is to set up sequences as if it were a video by means of the Show Picture command. Like the classic "Insert Coin" in demos while the game is on standby.

The process is tedious, but it can be a solution to some video sequences without the codec barrier.

This looks interesting even for Player frame-by-frame debugging without altering the event interpreter.

Exporting to PNG files or a single APNG file for lossy capture without relying on additional dependencies sounds good.

APNG has some advantages, e.g. the per-frame length is numerator/denominator based, so if there is some time without screen update, it could stop writing until screen gets actually updated/refreshed and write e.g. 2/60 if the same frame used two space frames.
