Experimenting with the sclang kernel for Jupyter suddenly brought this question to my mind.
This got me thinking about jit.pwindow and jit.window in Max as well. The Max console can only print text, of course. However, one can use rendered video and graphics within a patch. This led me to ask this question.
No. I only know that one can make the terminal background transparent in some OSes, and one can put a video behind the terminal window.
Not very often, but still, I should press alt/cmd + tab to find the window that sclang calls to move to the SC-IDE. This seems to lead me to the question…
Even if it were possible, it would be really hard work to implement. I should have thought of that before I wrote it. Sorry…
