#version HMCCS155FALL2002

/*
 * common shadow bug test - shadow testing casts a ray from the 
 * intersection point to the light and intersects it with the scene.
 * if they're careless, they'll count intersections that happen beyond
 * the light as casting a shadow and shadows will appear where they
 * shouldn't be.  in this case, there should be a white circle of
 * light from the spotlight, as well as the light from a pointlight.
 * both should be unobstructed.  if any shadows are present, they
 * have the bug.
