28// metafiles as graphic content, but do not implement using the contained clip
29// regions.
30// The given metafile will internally clip it's graphic content against the
31// included clip regions so that it is safe to ignore clip actions there. This
32// is not done completely, but implemented and extended as needed (on demand)
33// since all this is a workaround; the better and long term solution will be to
34// reimplement these im/exports to use primitives and not metafiles as base
35// information.
