Also added a required prerender function to scene and application.
This function is intended to be used as a way to prepare the scene
to be rendered in its current state. For that reason, the delta
time and the current clock tick are not passed to it.
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.
