Nice. I'm very glad they are doing that. But I am not going to support it, unfortunately.

There are lots of stuff ToDo in my engine and I barely manage two frameworks: native Win API and native X11. I even had to scrape the planned SDL2 support.
Supporting RPi was made possible as a manageably limited extension to the X11 framework, but that was the limit of my willingness to invest effort.
(I need RPi support for bragging rights mostly, I've been previously boasting Windows 98 support but, sadly, outgrew its limitations)

I should probably have been more clear: I'm interested if anyone did support RPi GLES using other Linuxes than Raspbian (I know there are a few)
