The reason was a synchronization issue.
Actually "LayerPropertiesNodeRef" is not a reference, but
a mirror copy of the LayerPropertiesNode the reference points
to. Changes to the original must be synchronized into the
reference and back.
This concept is a tribute to the original implementation and
the node reference was a convenience add-on to the iterator-
based API.
Better solution in general is to replace the LayerPropertiesNodeRef
concept with a real reference.
1.) Copy & Cut will now take the selection from
the transient selection if no real selection is present
2.) Hence, Copy & Cut are always enabled
3.) The same if true for duplicate
4.) Move interactive will also act immediately on the transient
selection.
- 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.
- force lower-case layer names to allow CIF/MAG loop (CIF needs
upper-case layer names, MAG doesn't)
- reverted CIF reader to standard
- new options for writer: tech, "zero timestamp".
- file name MUST be consistent with one cell name.
Reason: it's not possible to derive the initial
cell from the given options, so without the file name
being consistent, we can't know what to write there.
Basically the file name rather supplies the path.
The tech group is a new XML tag "<group>...</group>".
This tag is editable in the tech "general" page as "Group".
If non-empty, a submenu will be created in the tech selector
menu for all techs with the same group.
