Remove GetDictBy("DR") from annot/field dictionaries
We should not use DR field from annotation/field dictionaries, since these are not supposed to have one. In PDF spec 1.7, DR is defined only for the form dictionary, in 8.6.1. In addition, note 118 in Appendix H says "In PDF 1.2, an additional entry in the field dictionary, DR, was defined but was never implemented. Beginning with PDF 1.5, this entry is obsolete and should be ignored." The changes in CBA_FontMap fix the bug below. The changes in cpvt_generateap do not affect the bug but follow the reasoning from the above paragraph. BUG=pdfium:538 Review-Url: https://codereview.chromium.org/2337673002
