2017-05-24Use CheckedNumeric in BiInterpolImplNicolas Pena
This CL splits up BiInterpolImpl into the three interpolations its made of. In the interpolation, safe math is used, and a boolean keeps track of whether an overflow has occurred. If it does, we consider the patch to be invalid and immediately terminate the Draw method.

2017-05-23Make CPDF_ImageCacheEntry retain CPDF_ImageTom Sepez
CPDF_PageRenderCache::m_ImageCache is a map from streams to an image cache entry containing a clump of data associated with the stream. Oddly, the clump includes the stream key (which we already have in order to get to the clump), but worse doesn't ensure the existence of the CPDF_Image object which (maybe) owns the stream key in question. So replace the stream with a retained ptr to the image. Also renamed an unrelated member to avoid confusion with the CPDF_Object in play.

CFGAS_GEFonts are ref counted, and its a good thing since they are managed by at least three different font managers: CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these have a clear claim to ownership of the CFGAS_GEFont. CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and CXFA_PDFFontMgr, and they could each outlive the other. Thus the font needs to watch for destruction of either of its managers, so as to stop using it after its gone.

CPDFXFA_DocEnvionment is part of the heirarchy of objects owned by the embedder under its FPDF_Document object. IJS_EventContext is part of the hierarchy of objects owned by the embedder under its FPDF_FormHandle object. The FPDF_Document must outlive the FPDF_FormHandle, so there is a lifetime inversion with the m_pJSEventContext member. No matter, event contexts are transient and allocated in a stack-based manner as control bounces from C++ to JS and vice versa, and keeping a persistent one seems wrong. So make it only as needed.
