The following commit has been merged in the webkit-1.1 branch:
commit 558622d4ce6aa9bbd7819b1485bbccea206e0a54

    Add SPI to invalidate a WebView's backing store
    
    This is useful in conjunction with
    IWebUIDelegatePrivate2::drawBackground. This provides a way for the UI
    delegate to force WebView to get its background redrawn.
    
    Fixes <http://webkit.org/b/29737> Need SPI to invalidate a WebView's
    backing store
    
    Reviewed by Anders Carlsson.
    
    * Interfaces/IWebViewPrivate.idl: Added invalidateBackingStore.
    * WebView.cpp:
    (WebView::invalidateBackingStore): If rect is 0, invalidate our whole
    client rect. Otherwise invalidate the intersection of rect with our
    client rect.
    * WebView.h:
