        Move the undef try/catch to WebKitPrfix.h and include algorithm so we get
        exception_defines.h and so the undef of try/catch works.

        Break off the BGRA to ARGB code into WebGraphicsExtras.c, this lets
        WebBaseNetscapePluginView.m safely compile as ObjC++ and not cause the Accelerate
        framework to complain about C++ exceptions being disabled.

        * Misc/WebGraphicsExtras.c: Added.
