Build your own engine?

The Graffiks stack could be built up as an ultra-modular system, tailored to your needs:

"Graffiks" would be the engine core.

• If you want time management, grab a time management library
• If you want scene/object management, grab a scene manager library
• If you want particle simulation, grab a particle sim library
• If you want material management, grab a material libr....etc etc

To keeps thing easy for people who want everything, I could distribute a script that yoinks all the repos, combines all the header files, and sticks everything in one .so as a "complete" engine.
