This was wrong twice making it right... But let's fix that. The center was being passed as a DevicePixelPoint, but was in fact in CSS pixels, the size was passed as a Gfx::FloatSize but was in CSS pixels again. Then we were scaling from device pixels to CSS pixels when painting which does not need to be done if everything is passed which the correct scale factors already applied.
