------- Additional Comments from Nikolas Zimmermann <zimmermann at kde.org>
New attempt at fixing the rounding problems across the Gtk/Win bots.
It fixes all 0.0 vs -0.0 issues, several wrong sizes that are reported in the
mac dumps 481x360 -> 480x360.
This includes a patch from Zoltan to SVGPreserveAspectRatio::getCTM(), to avoid
loosing precision, by using double internally. The AffineTransform that
getCTM() generates uses double values, that's why this matters!
