Features in Office
Display the missing autoshape action information button.
There are some problems:
The filter produces odp file which is rendered correctly in OOo
draw:type is probably handled per shape in OOo and according the
specs "The draw:type attribute specifies the name of a shape
type that is rendering engine dependent" (try with koconvertor)
The shape, when scaled, does not scale in content-aware style,
try in OOo to scale it and it changes the geometry. If you convert
the shape in OOo to polygon, it behaves same as in Calligra
Thus he shape of the circle is ellipse in Calligra.
