Various glu* functions reported as deprecated

Hi, Not sure if you consider this a problem (yet) or not but a number of glu* functions are deprecated in OS X 10.9. The game builds and loads ok so if anything this is a low priority issue.

A sample is included below; other then those mentioned gluBuild1DMipmaps, gluBuild2DMipmaps, gluUnProject, GLUquadricObj, gluNewQuadric and various others are also reported. gluErrorString is reported more then all others.
