//-- diffuse lighting of type directional lighting:
//- similar to the sun light illuminated from a great distance away
//- using its direction the amount of light is determinable
//- unlike ambient lighting, no effect of surfaces it doesn't directly touch
//- requirements: direction and a normal polygon vector implemented in both pixel and vertex shader
