            Bug ID: 176936
           Summary: Web Inspector: make recording swizzle async

           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org

In the case that we need to swizzle a CanvasPattern, we need to wait for the required Image (first argument) to have loaded before we attempt to create the pattern.  The current swizzle logic is such that even though we use a dataURL, it is still possible for the Image to not have loaded by the time we want to create the CanvasPattern.  As such, we should make the entire the swizzle system async so that we can wait to create the CanvasPattern until the required Image has loaded.
