This function passes the CAVE library a pointer to your graphics initialization routine. Your routine should do any GL initialization that is required for your display functions. The rendering processes will call this routine exactly once, at the beginning of the next frame. CAVEInitApplication blocks until the next swapbuffers call by the rendering processes.
The first argument is a pointer to the graphics initialization routine. The second argument is the number of arguments that the graphics initialization routine receives (5 is the maximum). If your routine does not take any arguments, pass zero (0). The remainder are the arguments to be passed to your routine. These are stored as void *'s, and so must be pointers.
CAVEInitApplication should be called after CAVEInit, and before CAVEDisplay.
