Repaint issues with -webkit-svg-shadow used on a container
https://bugs.webkit.org/show_bug.cgi?id=65643
<rdar://problem/7600532>

Reviewed by Simon Fraser.

SVG renderer repaint rects are currently expanded only by the shadow of
the renderer itself; however, the area they need to repaint can be larger
than that, if their parents also have shadows. We need to take into account
parent's shadows (respecting transforms, as well).

clippedOverflowRectForRepaint already recurses upwards through the render tree,
and ends up with a rect in layout coordinates, so we manually apply the shadow
at each step (repaintRectInLocalCoordinatesExcludingSVGShadow was added to allow
us to get the raw repaint rect without the shadow baked-in).

repaintRectInLocalCoordinates now includes shadows from all parents.

Also, RenderSVGRoot was clipping repaint rects to the viewport before applying
shadows, so offscreen elements with on-screen shadows (applied by the root) would not paint the shadows.
We can just swap the order of these things to correct this.

Seam occurred between pieces of ShadowBlur on floating point zoom
https://bugs.webkit.org/show_bug.cgi?id=101435

Patch by KyungTae Kim <ktf.kim@samsung.com> on 2012-11-07
Reviewed by Simon Fraser.

When paint Shadow that doesn't have blurred edge on floating point zoom,
pixel seam (pixel cracks) occurred between pieces of the ShadowBlur because of unaligned clip rect.
So, enlarge the clipping area 1 pixel so that the fill does not bleed (due to antialiasing)
even if the unaligned clip rect occurred.
