All problems covered by existing LayoutTests. Unfortunately, when pixel tests aren't looked at, there is no way anyone could notice :( svg/W3C-SVG-1.1/masking-mask-01-b.svg - masks seem translated svg/custom/mask-inside-defs.svg - broken svg/custom/visibility-override-mask.svg - broken
Found the culprit: http://trac.webkit.org/changeset/31830/trunk/WebCore/svg/graphics/cg/SVGResourceMaskerCg.mm Uploading fix soon.
Created attachment 22744 [details] Initial patch Would be nice if David could have a look, as one of his refactorings broke SVG <mask> support.
