Again, this is implicit (and it really should've been documented better,
sorry), but the idea is that the compositor communicates its intention to
texture from the wl_buffer by creating the EGLImage for the wl_buffer. Once
it's done, it destroys the EGLImage. So once the EGLImage is created you have
to wait on the client-rendering-finished fence before first use, Once the
EGLImage is destroyed you signal the compositor-texturing-finished fence.
