           Summary: Turn ImageBuffer::image/ImageBuffer::imageForRendering
                    to ImageBuffer::image/ImageBuffer::copiedImage
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mrobinson at webkit.org


Most of the time ImageBuffer::image should be a live representation of an image buffer, but in some cases it should be a copy (e.g. creating patterns from 2D canvas rendering contexts). The current naming scheme was confusing enough that Cairo is making a large number of unnecessary full-canvas pixel copies.
