When converting from GDSII, there are attributes used in GDSII that are
not used by Xic. These attributes are saved as properties, and will be
added to any subsequent GDSII file produced. Also, the wire end style
is saved as a property of wires, since the CIF format does not provide
a variable for this.

- LabelSize Property: Property number 7180
This property is added to labels when writing to GDSII, and saves the
label width and height. The string has the format
width width height height
where width and height are in internal units.
- Text Property: Property number 7012
This property saves GDSII label parameters ANGLE, MAG, WIDTH, and
PTYPE, which are unused by Xic. The string consists of a concatenation
of keyword/value pairs, using the keywords above (not all need be
present). These attributes will be reassigned to the label when a
GDSII file is written.
- Pathtype Property: Property number 7033
This property is used for physical mode wires of nonzero width which
have a nondefault path type. The string has the form
PATHTYPE pathtype
where pathtype is 0 for flush ends, 1 for rounded ends. The
default pathtype is 2 (extended ends). This property is not added to
wire objects when reading GDSII, but is added to wires in native and
CIF output if the CifOldWire variable is set. The wire end
style is now included in the wire specification (see A.3.3) in
the present default syntax.
