    egl/wayland: Damage INT32_MAX x INT32_MAX region for eglSwapBuffers

    If we're not using EGL_EXT_swap_buffers_with_damage, we have to
    damage the full extent.  EGL operates on buffer coordinates, but
    wl_surface.damage takes surface coordinates.  EGL doesn't know the
    buffer transformation (rotated or scaled) and can't post accurate
    damage in surface coordinates.  The damage event however is clipped to
    the surface extents so we can just damage the maximum rectangle.

    In case of EGL_EXT_swap_buffers_with_damage, the application knows
    the buffer transform and is expected to pass in rectangles in
    surface space.
