As mentioned here: https://issues.apache.org/jira/browse/PDFBOX-2019, I'm trying to generate an appearance stream so viewers beyond Adobe Acrobat will correctly display annotations.
What exactly is supposed to go into the appearance dictionary for a PDAnnotationPolyline or PDAnnotationPolygon? Ref: http://pdfbox.apache.org/docs/1.8.9/javadocs/org/apache/pdfbox/pdmodel/interactive/annotation/PDAnnotation.html#setAppearance(org.apache.pdfbox.pdmodel.interactive.annotation.PDAppearanceDictionary)
