Support bug 235 by providing interface layers in graphics. First is the surface manager API, to be implemented in graphics.nokia, second is the adptation-to-adaption interface for the guestvideodriver and virtual video hardware. This allows graphics.nokia to provide a syborg version of surface manager driver based upon the guestvideodriver, implemented in the graphics.simulator package. This submission includes a version 2 syntax package definition file purely for those components of interest to bug 235. This makes selective compilation of the graphics package easier. A further submission will prune down the surface manager component in the graphics package.

This file is used to create a stub DLL for ROMs where graphics
resource isn't present, hence all functions are empty. However,
it is not expected this DLL will ever be loaded since the user
won't be able to create a RSgDrawable in the first place (and
this class is only used when trying to draw an existing RSgDrawable).
