* This attribute can only be used when the file represents a pattern in a material layer,
* e.g. copper, solder mask, legend.
* Together with.FileFunction it defines the role of that image in
* the layer structure of the PCB.
* Note that the .FilePolarity attribute does not change the image -
* no attribute does.
* It changes the interpretation of the image.
* For example, in a copper layer in positive polarity a round flash generates a copper pad.
* In a copper layer in negative polarity it generates a clearance.
* Solder mask images usually represent solder mask openings and are then negative.
* This may be counter-intuitive.
