gl3n has a really good API with regards to game development 
(resembling GLSL helps), although I guess changing to a more Phobos
style might be needed for inclusion. I think having it in the standard 
library would be extremely useful, though - no need to implement it myself
then. Typical matrices used in gamedev (4x4 etc) woud be really useful as 
well (as said before, I'd even like stuff like AABBoxes, but let's go for 
vectors/matrices/quaternions first .
