I wanted a unified framework for OpenGL on both OSX and iOS without to much of a hassle (less is more). Just to play around easily and to see what the differences are between OSX and iOS. However, the sample code "GLEssentials" provided by Apple was very outdated, so I modernized it.
## Changes include:
* Converted to ARC
* Usage of obj-c modules
* Usage of GLKit (instead of doing everything by hand with EAGLayers and the like)
* Removed their basic glUtils (as such functionality is in GLKit anyways)
* Restructered project and a lot of simplifications
