From d09a09751f724ecdb1a0bc307447a3d0c212ebff Mon Sep 17 00:00:00 2001

Subject: Replace wrapper methods in CPDF_Path with -> operator.

These just invoked exaclty the same methodes in the underlying
xxxData class, which we can now do with just a ->()

Move some methods to the xxxData class, where they belong.
In doing so, put MakePrivateCopy() calls at each callsite
for those methods that made a copy.
