<feImage> has problems referencing local elements

Reviewed by Zoltan Herczeg.

Source/WebCore:

<feImage> referencing local elements are currently rendered into an ImageBuffer
by SVGFEImageElement, using the local coordinates of the referenced renderer.

This approach is buggy and should be avoided, by moving the rendering fully
into SVGFEImage, which takes care of respecting the correct transformations.

This fixes <feImage> + local references, which currently breaks two tests in trunk.
Covered by existing tests.
