From Wojciech Lewandowski, "As suggested I have added missing method to PerContextProgram. Tested with our programs.

Browse Source 
I see that we should expect some performance penalty for using this method.  It won’t be painful in my current case because I have only a few animated characters. But I suspect  some day I will have to fix osgCal to use int UniformIds natively for larger crowds."
