           Summary: Implement asymmetric/symmetric stretching of vertical
                    operators
           Product: WebKit

            Status: NEW
          Severity: Normal
          Priority: P2
         Component: MathML
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fred.wang at free.fr
        Depends on: 99620


>From the spec:

"The symmetric attribute governs whether the height and depth above and below the axis of the character are forced to be equal (by forcing both height and depth to become the maximum of the two). An example of a situation where one might set symmetric="false" arises with parentheses around a matrix not aligned on the axis, which frequently occurs when multiplying non-square matrices. In this case, one wants the parentheses to stretch to cover the matrix, whereas stretching the parentheses symmetrically would cause them to protrude beyond one edge of the matrix. The symmetric attribute only applies to characters that stretch vertically (otherwise it is ignored). "
