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.
