Font disregarded in Freetext annotation with default appearance (DA) but without appearance stream (AP)

Description
Created attachment 141117 Test file with freetext annotation without appearance stream
Attached is an example file with a freetext annotation. This annotation has a default appearance (DA) but no appearance stream (AP). Poppler disregards the font of the annotation. While admittedly the file has been constructed by hand-editing (annotating the file in Adobe Reader and then manually removing the /AP part), it is nevertheless a standard-conforming file.
Fixing this issue is a necessary first step towards fixing https://bugs.freedesktop.org/show_bug.cgi?id=81748 .
I attach a preliminary patch which kind-of fixes the issue. 'Kind-of' only, because there are (at least) two issues with it:
-
poppler issues
"Syntax Warning: Unknown font type: '???'"
from the call to 'GfxFont::makeFont' in Annot.cc:2933
-
The text is moved a little bit towards the top of the page (notice how the top part of "This is a test" is cut off).
The fact that poppler renders the text in the wrong color (red instead of black) is a separate bug.
Test file and patch have been written by Tobias Deiminger, who deserves all the praise.
