    compositor: Fix culling of repaints behind opaque surfaces

    Culling of the repaint of a surface behind an opaque surface on the
    same plane was broken by commit 547149a9 [1]. The idea of that commit
    is that the damage obscured by an overlay would remain on the primary
    plane damage and be repainted when the overlay moved. However, in the
    case the two surfaces are on the same plane, the opaque one is not
    obscured, so it ends up being repainted.

    This commit adds an opaque field to struct weston_plane, that is built
    incrementally when accumulating damage. The opaque region of surfaces
    on the same plane are removed from the plane's damage, restoring the
    previous culling behavior. But since damage behind opaque region of
    other planes is maintained, the bug solved in the mentioned commit is
    not regressed.
