2016-05-25Remove CFX_PrivateData from CPDF_Documenttsepez
Replace it with two generic slots for Links and Codec usage. Since the codec is at a lower layer than the document, we don't provide separate get/set methods, since having a document upon which to call these would be a layering violation. Do the same for the Links for simplicity. Review-Url: https://codereview.chromium.org/2005193003
2016-05-25Remove CFX_PrivateData from CPDF_Pagetsepez
CFX_PrivateData served two purposes here: The first was to hold an opaque pointer to the corresponding page structure in the next higher layer, of which it knows no details. Introduce an empty CPDF_Page::View class to represent this higher class, so as to get type safety while preserving layering. The second was to hold an opaque render context, which it also happened to own. Make this a CFX_Deletable to help with management. Also remove an unused inheritance from CFX_PrivateData in CPDF_Annot. Review-Url: https://codereview.chromium.org/2008553008

2016-05-24Remove CFX_PrivateData from CPDF_ModuleMgrtsepez
Its only used to store one object, so replace it with a unique_ptr to a class with a virtual dtor. Rename the prototypical class with virtual dtor from CFX_DestructObject to CFX_Deletable. Rename the fx_basic_module.cpp to cfx_modulemgr.cpp to match the one class in it. Review-Url: https://codereview.chromium.org/2013483003

2016-04-29Relax a couple checks to allow certain non-standard PDF files.weili
Some non-standard PDF files misuse the size of cross reference table, and reuse some object number which the old one is still in use. PDFium can relax the reusing of xref objects only since it is not referred in the pdf document. When the size of cross reference table is larger than defined, PDFium will try to continue other than abort. BUG=chromium:596947 Review-Url: https://codereview.chromium.org/1926823002

2016-04-27Standardize on ASSERT.dsinclair
There are currently three ways to assert in the code (ASSERT, FXSYS_assert and assert). This CL standardizes on ASSERT. The benefit of ASSERT is that it can be overridden if the platform requies and we can pickup the Chromium version if it has already been defined in the build. This does change behaviour. Currently FXSYS_assert is always defined but ASSERT is only defined in debug builds. So, the FXSYS_assert's would fire in Release builds. That will no longer happen.
