SVG fix for broken radial gradient

This is the fix for the broken radial gradient. The adjusted focalPoint must be
moved by the centralPoint, because the base (the focalPoint) was substracted by
the centralPoint before. This issue was fixed in the cairo specific code, but
got lost with the platform independent code. It is also neccessary to make a
deviation of maximum 0.2% to get around the fixed point values in cairo.

I'm sure this patch will change some pixeltests. I also added a new pixeltest
but can't produce the results at the moment.
