2. Dashing (all annots). MuPDF ignores this proprty.
3. Colors and font size for FreeText annotations.
4. Line end icons also for POLYGON and POLY_LINE annotations.
MuPDF only honors them for LINE annotations.
5. Always perform a "clean" for the annot, because MuPDF does not
enclose their syntax in a string pair "q ... Q", which may cause
