    - Added an option for a postFX to get its viewport from a named texture
    in slot 0, if there is one.  This allows the postFX to operate when the
    named input texture's viewport is different than the current viewport.
    - Modified the SSAO postFX to use the new
    PFXTargetViewport_NamedInTexture0 option to more closely link SSAO with
    the prepass buffer.
    - Modifed the GFX method setActiveRenderTarget() with a new parameter
    that indicates if the current viewport should be modified with the new
    rendering target.  This defaults to true to maintain its previous
    behaviour.  The postFX rendering pipeline sets this to false as it now
    handles its own viewport setup, and removes an unnecessary
    GFX->setViewport() call.
