            Bug ID: 180104
           Summary: PostScript to PDF conversion should be done off the
                    main thread
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: sabouhallawa at apple.com

Currently the only way to draw a PostScript image is to covert it to PDF and use the PDFKit to draw the converted PDF. The conversion process is expensive. If the PostScript image is loaded as a sub-resource, other elements have to drawn beside this image. Converting the image to a PDF on a separate thread will allow other elements in the page to be drawn. This should lower the page loading time since the conversion happens only once when the image is loaded for the first time.
