           Summary: [chromium] Allow WebGestureEvent to store four
                    floating point values
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tdanderson at chromium.org
                CC: rjkroege at chromium.org


A first step to implementing master bug https://bugs.webkit.org/show_bug.cgi?id=83947. Currently a WebGestureEvent stores two floats (deltaX and deltaY) which are unused in Tap and Press events. This patch will add gammaX and gammaY members to WebGestureEvent so that (deltaX, deltaY) and (gammaX, gammaY) can be used to represent the top left and bottom right coordinates of the enclosing rectangle of the ellipse information associated with the touch event.
