            Bug ID: 196263
           Summary: SVGMatrix methods do not conform to the specs
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
          Assignee: webkit-unassigned at lists.webkit.org

The SVG 1.1 specs link is: https://www.w3.org/TR/SVG11/coords.html#InterfaceSVGMatrix.

The specs of the methods is a little bit vague. For example the multiply method does not clearly state whether the operation should change the SVGMatrix object i.e. "thisMatrix *= secondMatrix; return thisMatrix;". Or it is read only operation i.e., "return thisMatrix * secondMatrix".

But you can notice in the specs that SVGMatrix methods do not raise the exception NO_MODIFICATION_ALLOWED_ERR if the object is read only. Notice also setting the attribute 'a' for example may raise this exception. Therefore, I think the specs wanted to make these operations read-only. None of the methods should raise the exception NO_MODIFICATION_ALLOWED_ERR.
