           Summary: [Qt] Images scaled poorly in canvas
           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: allan.jensen at digia.com

The WebKit canvas code assumes that antialiasing and average image quality is enabled by default. The Qt ImageBuffer implementation does not however set any default render-hints causing the defaults in the GraphicsContext to be antialiasing and smooth scaling disabled.

Ideally these default should follow the render-hints set on the webview, but I don't see how that is possible currently, so let us default the defaults to the default.
