Certified primitives are harmless when used by old uncertified
parts, so there's no need to create special certified versions.
And in stead of fixing parts to reference the new names, you
might just as well certify the parts.

This flag is already defined, it is called "0 FACE DOUBLE-SIDED"
or "0 FACE UNKNOWN" !
It has the meaning that the next section of the dat file is
not certified, and ALL following faces (including those in
subfiles) should be drawn.
