Incorporated most of Emilo's changes. His VG changes lead to a panic from window server. It may be a circular deadlockproblem where Wserv is a client of EGL which is a client of Wserv, thus circular. Need to look at it further. I also fixed the arrangement of def files, and didn't take the VG mmp file changes, as I don't think they are appropriate to a stand alone real EGL implmentation. Still need to pull in Emilo's graphicscomposition changes.

/*
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).
