Tim Edwards 51b70f6577 Corrected an error in the LEF/DEF geometry reading, because I
discovered that not all LEF/DEF rectangle coordinates are in
canonical order.  Took the opportunity to update the LefError()
routine with an additional argument so that it can separate
errors, warnings, and informational messages, and will correctly
state whether the output is for a LEF or DEF read operation.

Tim Edwards 87c07451d1 Corrected the LEF read routine so that when LEF is read to annotate
an existing GDS file, the "LEFview" property is not set (i.e., it
should not be marked as an abstract view because it is still a GDS
view).

Tim Edwards 770a6f4a17 Updated the handling of fixed bounding boxes for abstract views
(once corrected in an experimental branch but never merged).  This
avoids changing the actual bounding box of the cell to match the
LEF bounding box, but defines a property instead and uses that
property for certain functions such as displaying the bounding box
outline or selecting the cell.  This avoids certain related errors
such as the failure to extract connections to areas outside of the
fixed bounding box.

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.
