gl3n has most features of GLM just the syntax is different and a 
few other things.

gl3n then operates on row-major matrices only (Extrawurst wanted 
to work on a column-major version), which isn't a big issue for 
your usual GL, you just need to tell OpenGL that it is in 
row-major format when uploading it.

iirc GLM is a header only library so you can't simply interface 
it from D you would need to port every function, that's what I 
basically did in gl3n only that I started from scratch and made 
my own API etc. So you can use gl3n as a glm replacement it just 
has a different syntax and a few semantics are different.

Regarding some functions not showing up on the website, that's 
because the ddoc generator doesn't want to go into some static 
if() or version() blocks. A known bug.
