I thought you did SVGZoomAndPan already?

[do-not-use, 2013/06/24 14:23:13]

This one is currently an exception and remains because it has
[SetterRaisesException] extended attribute while it isn't present in
SVGZoomAndPan. I think we'll need to add [SetterRaisesException] extended
attribute to this attribute in SVGZoomAndPan. The thing is that we'll need to
add an ExceptionCode argument to several implementation methods.
