Bug 49311 – Convert SVGMatrix/SVGTransform/SVGTransformList to the new SVGPropertyTearOff concept

• Component: SVG
• Status: RESOLVED FIXED

[Nikolas Zimmermann]

Unfortunately there was no way to split the patches up, w/o adding new "hybrid wrappers" that support an "old style" parent (SVGTransform) with a "new style" child (SVGMatrix)
SVGTransform contains "readonly attribute SVGMatrix matrix", so I had to switch them over to the new system in one go.
Unfortunately SVGTransformList/SVGAnimatedTransformList had to be converted as well, but those require a new SVGPropertyTearOff classes, that deals with the two extra methods that SVGTransformList provides (consolidate, createSVGTransformFromMatrix)

So the patch is a much larger than I hoped. Anyhow, after this patch there's only SVGPathSegList left to do! (And the cleanup patches removing the old JS/V8SVGPODTypeWrappers, and all the Deprecated* files).

Patch v2

Not sure why mac build failed, probably an unused variable. If it fails again, I'll try a release build.

This patch is significantly larger, as it contains several new testcases.

The error is real, I tried a build from scratch, and it turns out I forgot to add SVGAnimatedTransformList.h to Xcode, no works fine. Not sure if it's worth uploading a new version just for that though

We already talked about some issues on IRC, just add some notes to bugzilla review as well. I may forgot to note some change wishes here :-) Niko already fixed Mac.

Great Patch Niko! Looking forward to see the same work on SVGPathSegList :-D

Don't use String::format here ;-) We talked about this on IRC right now.

Can you rename t to transform please? And please fix the indentation as well on switch .. case later in the code.

Fixed all issues, landing.
