    [quartz] handle 0x0 surfaces.
    
    Some tests, like invalid-matrix, generate a 0x0 bitmap; in
    the quartz backend this caused a nil surface to be returned,
    whereas the tests expect a quartz surface. Other surfaces
    return a backend-specific surface with a zero-sized bitmap,
    quartz should do the same.
    
    Fixes the tests ft-font-create-for-ft-face, get-and-set,
    get-clip, invalid-matrix, line-width-zero,
    select-font-no-show-text, solid-pattern-cache-stress,
    surface-finish-twice, and text-cache-crash.
