option "labels ... cellid" to handle some vendor files where
apparently to get around the 30-character cell name limit, the
actual cellname is encoded on a text layer. Added new cifop
"boundary" (no arguments) for cases where a cell abutment box
is encoded on a GDS layer; this now translates the bounding
box to the FIXED_BBOX property, as is done with the LEF bounding
box. Also corrected the property set function to free existing
property value allocated memory when overwriting a property with
a new value.
were made where contacts are placed when shifting up on metal
layer but not made for the reverse case. Also corrected one
inconsistency with non-minimum width wires.
the same interpretation as the scalefactor for the DRC section:
Values in the section are interpreted as lambda divided by the
scalefactor. That allows the wiring values to be real units such
as nanometers and avoid problems with fractional lambda values.
centering wires on grid lines when using a snap grid) so that
the wire width is maintained when switching from one layer to
another, when the wire width is larger than the minimum for the
route layer.
addition to wire overlaps, and added a method when painting
contacts to draw the necessary wire extension past the contact.
Since the wiring method draws single contacts by default, this
wiring method assumes a change in direction between layers. But
the main point is to generate wire contacts without DRC errors.
the wires stay centered on a centerline with respect to each other.
Also corrected the long-standing minor issue that the outline
drawing of the wire does not update when using the mouse scroll
wheel, making it unclear that the wire size has changed until the
wire position changes.
