- completed RenderMan differences (FVar with creasing, chaikin, accuracy)

The compatibility portions of the "Porting Guide" are
now split into a different page. We'd like to keep
the "Porting Guide" simple and easy to understand.
The Compatiblity portion may live on longer than what
is just needed for Porting from 2.x to 3.0.
