When rendering Type 3 glyphs that contain stroke operations, Poppler will
render the stroke in the current stroke color instead of the fill color.
The PDF Reference states that the text rendering mode parameter which allows
fonts to be stroked and filled separately with the stroke and fill colors
does not apply to Type 3 fonts. Adobe Reader renders Type 3 glyphs
that contain stroke operations with the fill color.
Attached is a patch that fixes this bug.

Previously Type 3 glyphs that contain stroke operations for stroking
the lines with the stroke color.
