Summary

Added dual extrusion to the tags - pegs in one color, base in the other. Single extrusion is still supported, of course.

Info on the tags here: msdn.microsoft.com/en-us/library/ee804885%28v=surface.10%29.aspx

Tested working on the new surface as well - Samsung's SUR40. Height is less important now - the tags can be added as a flat 1/16" layer to any object. I use the tag outline in one color, the rest of the object (and thus the pegs) in another color.
