Redaction annotation contains malformed /OC entry
Acrobat produces /OC[0.858826 0.203918 0.145096] when a new redaction annotation is created. This appears to be an erroneous copy of the /C entry from the same annotation. Per Table 166 of the ISO standard, /OC is supposed to be a dictionary not an array. So it's not even well-formed, much less correct.
The /QuadPoints [] also looks dubious. It should be absent, not empty?
In terms of efficiency, a number of other entries are present which have no effect since other entries over-ride them. For example the /DA when /OverlayText is the empty string. And in fact the OverlayText itself. And so on.
To reproduce: add a redaction annotation in Adobe Acrobat and save without applying the redaction.
