----------------------------------------------------

This is an older version of a GPU Quaternion Julia ray tracer.  This
version should run on many cards supporting PixelShader 2.0, though
some cards may not support enough instructions (~1024) for it to run.
The program requires Cg, available from:

 Controls:

        space:                toggle morph animation
        r:                    automatically rotate Julia set
        i/I:                  increment/decrement 1st imaginary component of Julia set constant
        j/J:                  increment/decrement 2nd imaginary component of Julia set constant
        k/K:                  increment/decrement 3rd imaginary component of Julia set constant
        l/L:                  increment/decrement real component of Julia set constant
