record
Records every frame of the window as a movie until no record: record "clip.apng" makes an animated PNG with nothing else installed, and record "clip.mp4" (also .mov, .webm, .mkv and .gif) makes a video with ffmpeg, when it is installed. Each frame the sketch draws is one frame of the movie, played at 60 frames a second. A plain name goes in the sketch's output folder, an absolute path is used as it is, and the folders are made. The movie ends at no record, or when the window closes.
