'Surfaceless Upstream Surface'
Preparation for Bug 1068: GLContext creation and makeCurrent without default framebuffer
- Unify EGL surface related code in EGLSurface
- EGLWrappedSurface -> EGLSurface,
which utilizes a more straight forward
foreign upstream surface (X11, GDI, ..) to EGL mapping.
This also addresses Bug 1096, i.e. EGL Cleanup.
- Add notion of 'Surfaceless Upstream Surface'
- Add surfaceless 'fake' upstream surface hooks:
- EGLUpstreamSurfacelessHook
- X11UpstreamSurfacelessHook
Utilizing the ProxySurface option bit 'OPT_UPSTREAM_SURFACELESS'
signaling usage of 'no surface'.
- Add GLDrawableFactoryImpl.createSurfacelessImpl(..)
