Compares the layer values saved in a layer state to the current layer values in the drawing. This method compares everything except layer description. This method can also use VPLAYER and override settings of a viewport for comparison of visibility and overridable properties. Specify Null for the idVp argument to ignore viewport settings. 

Returns true if the layer state matches the layers in the drawing, false otherwise.
