Outlines, dashes, arrowheads and ink strokes were drawn under the full
transform, including the mapping of the group's child coordinate space onto its
box. A group whose children use small legacy child coordinates (scale ~1600)
therefore stroked 0.75 pt lines about 1200 pt wide and covered the slide. Inside
a group the outline is now carried through that mapping and stroked under the
slide-level view, so the line width, dash lengths and arrowhead sizes stay in
points, also for groups scaled unevenly.
