Numerical issues on Windows CE caused some image comparisons to fail.

On Windows CE and possibly Symbian some filtering and blending functions
of the SVG renderer will alter different pixels in two otherwise
apparently identical images. Until this is not addressed in the
renderers an exact image comparison is not alsways successful.
