           Summary: Performance: stop recomputing SVG path data twice
                    during layout
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: pdr at google.com
                CC: zimmermann at kde.org


We currently recompute SVG path data twice during layout, but we only need to do this once. This is especially bad in the case of circles and ellipses, where each call to createShape() ends up creating 4 expensive cubics.

Patch forthcoming!
