Tim Edwards 7e738576bc Corrected errors in LEF output syntax (missing semicolons at
statement ends on properties imported from a LEF file).  Never
noticed before because writing LEF after reading LEF was unusual.

Tim Edwards f6d4da56ce Extended the "lef read" command when used to annotate existing cells
so that PIN information including USE and CLASS are added to port
labels (previously only the bounding box was annotated).

Tim Edwards 5693729ad5 Added code to avoid mishandling negative layer numbers when a
label in a DEF file is on a layer that has not been properly
mapped to a magic layer.  This would apply a negative index to
a TileType bitmask and crash the program.  Also:  Changed the
style and colormap slightly to make the via2 and via4 styles
more visible.

Tim Edwards 193493a0cc Corrected an error in the DEF file read routine's check on via
DRC rules, which was conflating magic and CIF tile types,
resulting in incorrect reading of via layers.

Tim Edwards 4ae868802d Modified the LEF read routine so that it determines the LEF-to-
magic conversion for making magic contact types from contact cuts
from the CIF/GDS input rules rather than the output rules.  This
generally makes more sense, plus avoids conflicts where the output
rules may be set for CIF-DRC checks and may not be appropriate for
LEF input without changing the style.

Tim Edwards ccbd6727d1 Enhanced the LEF file parser to handle many more standard keywords
without throwing an error message.

Tim Edwards 088fc759c4 Set of changes updating version 8.2 to the level of 8.1, since 8.2
development had been halted since it was first created back in April.
Version 8.2 is now the official development version, with the first
development push to create a Cairo graphics interface.
