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