commit 0cabffc05f3b40f5ee897df73475e09a3c05fc7
tools::PolyPolygon -> basegfx in canvas
and
commit 2c5d5a6d55a1ebd153f05523972a2c625484bde2
tools::PolyPolygon -> basegfx in filter

Comment from quikee:
The interpretation of integer polygons and floating point polygons
(or any other float vs. int drawing primitives) are different,
so you have to be really careful when changing, that the result
after the change is still the same. A big problem is that we still
have the metafile in OutputDevice, which is completely integer based
- so there will be conversions that go from int representation to
float representation to int again and to float (because backend is
in floating point) and I really fear that because of this there will
be regressions and even if not, it could make changing later more
painful. This is the reason I wouldn't change these things without
having tests that would show when there is a difference in rendering.
