Bug 1351440 - Part 2. Encapsulate DrawResult and imgIContainer::FLAG_* into imgDrawingParams, and pass it to PaintSVG. r=jwatt The DrawResult return was not in fact anything to do with the success or failure of that method, but was actually passing out a very specific piece of information about the success or failure of any imagelib drawing that may not have occurred under the various PaintSVG calls. The signature of PaintSVG is changed from DrawResult PaintSVG(...., uint32 flags); to void PaintSVG(...., imgDrawingParams& aPackage); imgDrawingParams wraps DrawResult and imgIContainer::FLAG_* as a pack, pass through PaintSVG to imagelib draw calls under beneath.
