Make CPDF_ClipPath have a CPDF_ClipPathData rather than inheriting.
Make Data private to the ClipPath class which manages it
transparently for its callers. This prevents the callers
from having to remember to make a copy before dirtying the
shared data, since the operations that modify state will do
this under the covers for us.
