Yep - that's the revised version that I came up with during lunch, after I
scratched my initial suggestion.
Normalize the normal vector.
Normalize the Light source vector.
Have the normal function take a parameter that gets clamped to 0-1.
Then interpolate over the line segment extending between the actual normal and
the light source based on that parameter. No angles, no atan2, no matrix
