Hereby I use the setup and framework from last year's FrOSCon talk to bootstrap the demo example code for the talk at FrOSCon-26 Notably, the modern OpenGL output pipeline based on EGL is intended for reuse. Insights in this code were based essentially on existing code bases under GPL. Furthermore, using GPL is seen as a statement in support of "The Commons"
