           Summary: Coordinated Graphics: Remove tiles of a layer when
                    they are off the viewport.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: luxtella at company100.net


We need to remove tiles of the layer with the special properties: a transform animation and non affine transform. If a page has a lot of layers with a transform animation, we can encounter OOM. 
For example, we create tiles endlessly in http://www.satine.org/research/webkit/snowleopard/snowstack.html
