Hey guys!
Can you explain me how mantra calculates derivatives? I know they depend 
on topology of geometry. Does they depend on vertex order? I'm playing 
with anisotropic shader based on dPds, dPdt and do some test. Each test 
gives me an unpredictable result.
Don't let me die from this headache, please!
