            Bug ID: 189873
           Summary: DisplayList should record and replay back the painting
                    of the form controls
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

The form control drawing will recorded as a paintRect and a callback. If the GraphicsContext is recording, the paintRect and the callback will be stored. Otherwise the callback will be called by passing the GraphicsContext and the paintRect. The callback will be a lambda expression which captures whatever it needs to draw the form control. Since the renderer outlives recording and replaying back the display list, it can be passed by reference.

I am going to enable display list drawing temporarily till the layout tests pass on all bots.
