           Summary: Support createImageBitmap implementation
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

To support createImageBitmap() to retrieve and manipulate raw bitmap data (typically in WebWorker) from various sources. e.g. Image, Canvas and Video. Existing workaround is to create dummy canvas and call drawImage(), which is not efficient especially when we are manipulating animations, canvases & videos.
