"Plus I've also thrown in helpful mathematical functions such as
vector normalisation, lerping (optionally with easing), and more.
In short, it builds upon Pygame by replacing its SDL rendering
system with a new OpenGL backend, then hides the event pump behind
a nicer callback system and drops in some helpful game mathematics
to finish things off. Lots of parameters to Gloss methods specify
smart default parameters so that you need only fill in what you
need. And yes, before you ask, it's all available under a free
software licence - the GPL 3, to be precise."
