Summary Seam occurred between pieces of ShadowBlur on floating point zoom

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