[ Code ] Scene Page flags getter method

(From my unreleased thumbnail utility.)

  #{ get_page_flags( page )
  #
  #  Returns the flags bitmask for a Sketchup;;Page.
  #
  def get_page_flags( page )
    return 127 unless page.is_a?(Sketchup;;Page)
    flags = 0
    flags +=  1 if page.use_camera?         # Camera Location
    flags +=  2 if page.use_style?          # Drawing Style
    flags +=  4 if page.use_shadow_info?    # Shadow Settings
    flags +=  8 if page.use_axes?           # Axes Location
    flags += 16 if page.use_hidden?         # Hidden Geometry
    flags += 32 if page.use_hidden_layers?  # Visible Layers
    flags += 64 if page.use_section_planes? # Active Section Planes
    return flags
  end #}
