A user defined shape to see the wrong behavior

Open attached document in PowerPoint. It has a shape with a custGeom, where the
path has got w and h attribute, which defines a local coordinate system (a
'viewBox'). The shape has a handle. Drag it to verify that it works.

Open the document in LibreOffice. Notice, that the handle marker is not at the
corner of the triangle. Drag the handle. The triangle changes as expected.
Release the handle. Notice, that the handle is not shown where you have
released it, but at a place left from it.

The reason is, that when LO gets the handle position from the shape, it applies
the scaling again, which is needed for fitting the outer to the inner
coordinate, although the value of the handle position is already scaled in case
of OOXML-shapes.

The "cloudCallout" is the only shape from the preset, that uses a path
coordinate system. But because of bug 115813 you cannot use it, for testing
this bug.
