"replace" as the 2nd argument. This allows a simpler 'tag add
<command> <value>' than the existing awkward 'tag <command>
"[tag <command>]; <value>'. Using "add" also helps avoid
mistakes like one that was in the code for a long time which
overwrites one of the helper window callbacks. With this done,
added some additional callbacks to the "library manager" to
update when a new file is created by "select save" or "writeall".
Also added "Refresh" buttons to these windows, just in case.
Implemented a zoom function on the mouse scroll wheel when the
Control key is pressed. This is a stop-gap for a problem with
overriding button bindings that re-establish themselves when the
tool (box, wiring, etc.) changes. That needs to have a more
comprehensive solution (such as tool-specific bindings).
and merged the contents into drcmgr.tcl, with a new button in the
DRC manager for saving the DRC contents. Loading is somewhat less
useful since the DRC error tiles are interactive. The DRC manager
still has the issue that every checked edge becomes a separate
entry; this is an artifact of the way the DRC checker works, but
it creates large numbers of error areas, many of which are redundant.
categorized by error type and scrolled through conveniently. However,
it needs work dealing with finding the actual error bounds. The
"DRC count" counts tiles, which is tile-plane-geometry-specific, and
"DRC listall why" fractures errors both over tiles and over the square
areas that the interactive DRC splits the layout into, for performance.
The DRC error plane needs to be changed to hold different types for
each error class, so that errors can be scanned by boundary instead of
by tile (work to be done).
