        SVG feImage support
        https://bugs.webkit.org/show_bug.cgi?id=31905

        This implements the SVG Filter effect feImage with support of fragment urls.
        It also includes a bug fix for feComposite. feComposite didn't cover values
        bigger than 255 correctly on composite oeprator arithmetic.

        Tests: There are already many feImage tests in trunk. They just needed updated
               pixel test results.
               The feComposite bug is covered by svg/W3C-SVG-1.1/filters-composite-02-b.svg
               and depends on feImage.

        https://bugs.webkit.org/show_bug.cgi?id=31905

        The implementation of feImage requires pixel test result updates of the already
        available tests.

        There is also an update for svg/filters/feComposite.svg, since the patch also
        fixed a bug in feComposite.
