2018-05-01Check for NULL XFA context even when XFATom Sepez
Use strict typing for FPDF_Page to ensure we don't fall into code that expects the other page type when continuing from null context case.

2018-05-01Make FPDF_Document always be CPDF_Document.Tom Sepez
Greatly minimize the impact between going back and forth from XFA being on/off, so that XFA case is just an extension beyond the non-XFA data structures we've shipped for years, instead of being a complete replacement of them.

2018-05-01Introduce the concept of CPDF_Page::ExtensionTom Sepez
Similar tp CPDF_Document::Extension, this is a base type for fpdfsdk/ to use to improve layering. While we're at it, make pages point to documents to prove they don't outlive them. Another small step towards not passing XFA objects across FPDF.
