Use glm for matrix math instead of the OpenGL stack
Should cause less GL pipeline stalling / driver spinlocking if enabled. Disable AQUARIA_USE_GLM (default: true) in CMake to use the old GL pipeline version. Based on the implementation by Matt Bierner: https://bitbucket.org/mattbierner/ios-aquaria
