Minor change to AP generation logic
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".
