- Fix for merge issue when merging a document to current document using an intance of another document as opposed to using a file name. The save operation does a duplicate resource optmization which was incorreclty detecting two different Form XObject resources as identical.
- Added PDF Creator document attribute that can be used to set a maximum limit on the number of clipping operations, "MaxClippingPathPoints". This is a work around for some PDF file that the PDF Creator takes a very long time to render.

- Changed default margin to 0. This is the first build of Apryse PDF Converter now.
