        <rdar://problem/5410937> HIWebView in SimpleCarbonWeb doesn't seem to be getting adequate invalidation when window is resized

        This is a more localized fix for yesterday's change. Now explicitly call _web_layoutIfNeededRecursive inside the
        HIWebView Draw() function. Adds a FIXME to explain that we need to do layout before Carbon has decided what regions to draw.
        Doing layout in Draw() will potentially cause drawing to happen in two passes, but this has always been a problem in Carbon.

        * Carbon/HIWebView.m:
        (Draw): Call _web_layoutIfNeededRecursive on the main WebHTMLView.
        (SetFocusPart): Fix to work in ObjC++ (now that HIWebView.m is treated as a ObjC++ file.)
        * WebView/WebView.mm: Removes the 4 displayIfNeeded methods from yesterday's change.
        * WebKit.xcodeproj/project.pbxproj: Force the file type of HIWebView.m to ObjC++ so WebHTMLViewInternal.h can be included.
