* The original issue ("sw" etc for "tri")
* Implementing "magscale"
* Interpolation of environment variables on paths
* Warnings include file positions now
* Ignoring "<< properties >>" pseudo-layer
* MAG writer uses zero-area boxes for empty ones
* New test
- The MAG reader now has access to the details of the proposed
technology (set in KLayout), specifically inside library paths
($(tech_name), $(tech_dir)). This allows setting the MAG reader
path relative to the technology path.
- If no specific technology is set before MAG files are read and
the technology listed there is found in KLayout, KLayout will
attach the layout to this technology.
