elipzer 75357b330c Added Dependency: GLM
Now using GLM instead of the custom math libraries.
Sadly, this did not 100% fix the problem at hand but it does give
some closure that the math is not the problem.

Also it will be nice to have a general math library to not have to
deal with creating every math function every time.
