[PD] RaspberryPI GEM

[Dan Wilcox]

Yeah, actually I think it's *more* possible now with the RPi 4 than before, but it's not really officially supported since the hardware is optimized for ES. I also did a quick search to double-check.

What is needed is to modify GEM to work with ES and the RPi's EGL implementation which allows you to run GL stuff without X windows directly for the terminal. OpenFrameworks has supported this back to around 2011-12, so there is a good place to look if anyone wants to tackle it...
