Example PDF

Mupdf does not respect the "CA" entry that is allowed for all "markup annotations" (which includes most annotation types, e.g. square, etc). This is evident in some of the annotations on a sample PDF I found on another bug, which I'll attach here - see for example the pink-colored text box on page four, or the filled oval on page 12.

I have a patch to fix this which I am happy to provide - the main reason I am not doing so now is that we aren't handling the "Resource" dictionary in the cleanest way - some annotation types need to e.g. add fonts, etc - and so it might make sense to refactor that first.
