Subject: Merge CFX_PathGenerator into CFX_Path.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The CFX_Path was the only user of the CFX_PathGenerator which in turn just
proxied to the CFX_PathData. This CL removes the CFX_PathGenerator and merges
the code up into CFX_Path.
