I wrote my own framework and it uses some OpenGL calls, I have my own direct replacements for these calls.
But Xcode complains when I try to integrate these calls into a NSApp that all of these calls are deprecated.
It must be in some module that Appkit or Cocoa uses to include all the headers as I went through and eliminated all potential references.
I could just encapsulate all of this in a separate C or C++ file, but I would rather write it all in Obj-C.
I know it's just a warning, but I like to treat warnings as errors to catch as many bugs as possible.
