Compile a program binary. For this to work setProgramBinary must have been called on the osg::Program with an empty ProgramBinary prior to compileGLObjects being called. compileProgramBinary should be called after the program has been "exercised" by rendering with it. The ProgramBinary can then be saved to disk for faster subsequent compiling.

Alternative version of getUniformLocation( unsigned int uniformNameID ) retrofited into OSG for backward compatibility with osgCal, after uniform ids were refactored from std::strings to GLints in OSG version 2.9.10.
Drawbacks: This method is not particularly fast. It has to access mutexed static map of uniform ids. So don't overuse it or your app performance will suffer.
