Re: [9front] Blie - blended layers image editor

paint(1) has some nice design choices. following programs like sam
and acme, you can do things like this:

          <command
               Executes command and reads the canvas from its standard
               output.

          >command
               Executes command and writes the canvas to its standard
               input.

          |command
               Transforms the canvas by piping it through command.

this allows a lot of features to be towed outside the layer-compositing
program entirely, and any such tools can also be reused for other
applications.
