JP,

Thanks for looking at this.  I agree that the layer number is not
readable.  Do we have any code in place to select the layer number by
the description?  If not, I'll have to add that in order to load the file.

Either that or a comment that the units used within the file are in
millimeters.  I don't think the design goal was to support different
units in the file itself unless I missed something.
