           Summary: Improve renderer classes for MathML Token elements
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: MathML
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fred.wang at free.fr
            Blocks: 44208,57695,99620,124128


Proposal:

- For MathML Token elements, create a renderer class that use an anonymous wrapper to store the child nodes and add CSS style.

- Make MathMLOperator inherits from this class. This will allow to apply start/end margins to implement lspace/rspace (bug 99620)

- For <mi>, this will allow to apply CSS italic only when necessary (bug 44208)

- For other elements like <mtext>, allow to have non-text children, like what foreignObject does (bug 124128)

- Implement addChild/removeChild and attribute changes correctly (bug 57695)
