2017-06-22Minor change to AP generation logicJane Liu
Current behavior: Our CPVT_GenerateAP::Generate*AP() functions do not get called as long as the annotation dictionary has an "AP" entry. Problem: We always need the "N" entry in AP dictionary to display an annotation. Even though the spec requires "AP" dictionary to have an "N" entry for normal mode appearance, in case of a malformed pdf with "AP" but without "N" in "AP", we won't be able to display the annotation at all. Fix: Always check if "AP" has "N" entry to decide whether AP needs to be generated. If not, then we still need to generate AP, and add to the AP dictionary under the key "N".

It's possible to create a stream of length 0 in a PDF document. Currently the code will early exit and return a nullptr. This causes issues when you want to print the given PDF as the FPDF_ImportPages code ends up only generating up to the zero length object. This CL allows creating streams with length 0 and updates the PDF saving code to output a blank stream.
