Is it possible to have sort of a hybrid terminal that can display isolated images in one or more designated panes?
As I understand it, modern terminals are graphical emulations anyway, so obviously they have the underlying capability to display images.
The way I envision this working is one of two ways:
(1) have a designated or named area of the screen for graphics and the terminal text would wrap around it, or
(2) the images would just print inline with the lines of text; so you would give a command like "show mypicture.png" and the picture would appear below the current line and just scroll off the screen as more commands were entered.
Option (1) would make more sense for a curses-type environment where the application had 2D control over the terminal.
