SyncTERM’s Application Program Commands (ESC _ SyncTERM:... ESC \),
as CTerm documents them: a cache of files the BBS stores on this
machine, pictures (PPM and JPEG XL, from the cache or sent inline)
drawn anywhere on the screen with clipping, flips, zoom and masks, and
copying and pasting pixels. Synchronet’s graphical doors (SyncDoom and
the like) draw with these.
Pixels are drawn over the screen’s cells (see
Screen::draw_pixels), so text written later replaces them, as in
SyncTERM.
