Elias Naur 8db77e180e support stroked fills for clips, images
This change completes general support for stroked fills for clips and
images.

Annotated_size increases from 28 to 32, because of the linewidth field
added to AnnoImage. Stroked image fills are presumably rare, and if
memory pressure turns out to be a bottleneck, we could replace the
linewidth field with a separate AnnoLinewidth elements.

Updates #70
