           Summary: RenderSVGContainer (<g>) should not repaint when its
                    bounds change (unless it has a filter)
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: eric at webkit.org


RenderSVGContainer (<g>) should not repaint when its bounds change (unless it
has a filter)

The only time a <g> actually causes pixels to be rendered to the screen is when
it has a filter.  All other times, it shouldn't need to do any repainting.

Currently if you have an item moving inside a large <g>, causing the bounds of
that <g> to change, the entire <g> will repaint!  I've attached a patch which
addresses this, but seems to expose another repaint issue (or two), so it can't
be landed at this time.
