           Summary: Avoid painting non-foreground phases in RenderSVGRoot
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Enhancement
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org

As suggested in https://bugs.webkit.org/show_bug.cgi?id=82059 :

> (From update of attachment 134135 [details])
> The only renderer that used to care about phases like HitTestFloat or HotTestChildBlockBackgrounds is RenderSVGFo. Now that this dependency is gone, we can completely avoid painting() the whole SVG subtree in non-foreground phases (still exceptions are needed for PaintPhaseSelection I think) - that would save a lot of time!
