Hello, i spoke with Camilla about the issue, the "proposed" patch in this
mail is not ok because due to that bug the transformation doesn't have to
be applied to everything, but only to part of the shape, as it is already
done.

I did some testing with other shapes in Krita and Inkscape/LibreOffice
(even though i couldn't import their .odg because Krita has problems with
them), and clearly the problem presents itself only with path shapes,
because with the other shapes the matrix is used to transform the entire
shape.
So either Krita follows how other vector editors works, and then it doesn't
permit a layer transformation unless it "rasterize" it as an image, or
Krita has to subclass KoPathShape to change its behaviour.

In both cases KoPathShape has to enforce that when setting a matrix the
control points has to be mapped to it, as it happens when handling the
shape with the correct tools.
This is because as far as i can tell Calligra want to be faithful to how
the other vector editors work (and correctly load their shapes) and the
special use is done "only" by Krita.
