does not appear. Note the default value for a newly-inserted picture is
`MSO_AUTO_SHAPE_TYPE.RECTANGLE`, which performs no cropping because the extents of the
rectangle exactly correspond to the extents of the picture.

expected) or has custom geometry, like a freeform shape. A picture with no geometry will
have no visible representation on the slide, although it can be selected. This is because
without geometry, there is no "inside-the-shape" for it to appear in.
