Free text annotations in Canvas feedback should conform to PDF 1.7 specs

    When users use Linux, the PDF downloaded from the feedback viewer loses all free-text annotations in their viewer (mostly poppler based). It seems that these annotations in the PDF generated by Canvas are missing a 'DA' tag, which is required according to PDF spec 1.7

     

    Since Adobe Acrobat Reader is no longer available for Linux, can Canvas support other viewers for their annotated PDF's outside of the docviewer in Canvas by addind these 'DA' tags.
