            Bug ID: 186751
           Summary: Remove the SVG elements' attributes macros
           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

Each SVG element has to define its attributes via a set of macros. These macros, define the class member, the setter, the getter and the tear-off object creator. These set of macros have the following problems:

-- There is no way to debug through these macros.
-- The type of the the attributes' owner is not strongly typed. See the casting in SVGAnimatedPropertyMacros.h.
-- There is no actual inheritance between the C++ classes. For example SVGRectElement and SVGCircle both inherit SVGExternalResourcesRequired but they both have to hold a member named m_externalResourcesRequired.
-- Customizing the synchroniable attributes are awkward. See customizing m_orientType in SVGMarkerElement and m_textLength in SVGTextContentElement.
