            Bug ID: 261630
           Summary: Avoid computing layer bounds in
                    BackingSharingState::isAdditionalProviderCandidate()
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Compositing
          Assignee: webkit-unassigned at lists.webkit.org

The calls to calculateLayerBounds() in BackingSharingState::isAdditionalProviderCandidate() show as very hot on profiles on a page with many (thousands) of backing sharing candidates.

We have already computed layer bounds, so we can just use the ones we've computed in OverlapExtent.
