Fixes filter shear-free transform applied to SVG images.

Source/WebCore:

In applyResource() the shearFreeAbsoluteTransform is applied to the drawing region,
which is based on the object bounding box (which doesn't move). For a rotation
around the centre of the box, this should really just be the identity matrix,
since the BB should neither change size nor location. So really, we're just interested
in the scale change of the BB here, and not in moving it.

This impacts how slices are extracted, and affects the {x|y}Mid and {x|y}Max extractions
for vertical and horizontal slices, so the test verifies these.
