This essentially reverts the changes from
c230546a2c but implies new semantics.
Namely, surface-attached contexts can now be bound to EGL_NO_SURFACE if
the windowing system isn't ready yet.
It is the task of the windowing system to make sure the context is
properly rebound when the contents become available.
We ensure this by checking in begin_frame() if we created the EGL window
and if we did, we make_current(). This works because creating the EGL
window creates the EGL surface and that does a clear_current(), so this
is always going to have the desired effect of re-making the current
context.
It is very convoluted though.
