recreate

Recreate the EGLSurface, using the new EglBase. The caller should have already freed the old EGLSurface with releaseEglSurface().

This is useful when we want to update the EGLSurface associated with a Surface. For example, if we want to share with a different EGLContext, which can only be done by tearing down and recreating the context. (That's handled by the caller; this just creates a new EGLSurface for the Surface we were handed earlier.)

If the previous EGLSurface isn't fully destroyed, e.g. it's still current on a context somewhere, the create call will fail with complaints from the Surface about already being connected.
