2017-03-14Convert CPDF_Creator::m_Pos to uint32_tDan Sinclair
Currently m_Pos is a FX_POSITION. The value stored into the void* is typically a uint32_t. We sometimes read that uint32_t value as a size_t to compare against vector lengths. This Cl converts all usages to be uint32_t and uses pdfium::CollectionSize to get the correct typed vector size.

2017-02-28Avoid crash above CFWL_ListItem::GetText()Tom Sepez
The issue at hand is caused by a raw pointer rather than a retained pointer in InheritedData::m_pFontFamily. But the larger issue is that it's bad to Get() raw pointers from these, especially when its so cheap to pass them by const reference. One reason to Get() a raw pointer is to aid in down-casts, so add a helper to CFX_RetainPtr to give us downcasted retained pointers.

2017-02-27Allow building XFA without additional codecs.Tom Sepez
This is something we'd like to try for initial XFA launches adding in codecs as justified by results in the wild. Adding statistics for the unsupported cases is a follow-up exercise once this builds correctly. We always build all the additional libraries, to allow fuzzers to link against them even if we are not shipping them. The linker will sort it out for the actual code. Rename some files to match the classes contained within. That the existing tests seem to pass with the codecs disabled warrants further investigation.
