Thanks for the reference.
My question then: is mandatory to call eglSwapBuffers() to ensure
wl_egl_window_get_attached_size() returns the right window size? Because I
found nothing related about this. If it is mandatory, then calling
eglSwapBuffers() in the test should fix the problem (including the patch I've
summited with Daniel's changes).
