           Summary: Should get rid of TileController's
                    CoverageForSlowScrolling mode
           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: bdakin at apple.com


We should get rid of TileController's CoverageForSlowScrolling. The mode creates large tiles so that we will paint less for these sites. At one time, that was an important performance improvement because a lot of sites were still in slow scrolling mode. Now that very few sites fall into that mode, we should get rid of it since it just adds complexity.
