           Summary: [Texmap] Make TextureMapperLayer clip
                    m_state.needsDisplayRect with the layerRect.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: luxtella at company100.net


Currently, TextureMapperLayer creates a imageBuffer as big as
m_state.needsDisplayRect. The size of m_state.needsDisplayRect can be bigger
than the size of the layerRect, so we may consumed the memory more than the size
of the layerRect.
This patch makes TextureMapperLayer save the memory.
