           Summary: Make WebKit expose extra touch information
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: miletus at chromium.org


Some touch devices provide, other than (x,y) location, extra touch information, like the major/minor axis length, and  
the orientation of the touch ellipse. Attached is a proposed patch that routes these extra touch information through
chromium port to WebKit and exposes them to DOM.

WebCore::Touch is augmented with three fields :
m_radius ,  the major axis length of the touch ellipse
m_ratio  ,  the ratio between major and minor axis length of the touch ellipse
m_angle  ,  the orientation of the touch ellipse


The extra touch information is passed in from chromium's representation of touch event
WebKit::WebTouchPoint and then routed to platform touch event WebKit::PlatformTouchEventBuilder

Touch.idl and Document.idl are modified to expose these extra fields to DOM.
