Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
- prerequisite for holes as first class objects code
- introduced the OWNABLE_ITEM interface that defines the owning container (NODE/other ITEM/ITEM_SET)
- simplified the ITEM_SET interface
- constified a lot of APIs (ownership/JOINT management) as a side effect
Rebased and cleaned up by Jeff Young <jeff@rokeby.ie> 5 April 2023
- some STL cover types removed
When counting items, many cases exist where we want to count all items
without checking flags. This short-circuits the loop to provide the
immediate count.
- PNS_ITEMSET now keeps ownership info (does not rely on PNS_ITEM::Owner(), avoiding the risk of dangling pointers)
- fixed vias losing connected traces when dragging in mark obstacles mode
- fixed rare segfault when board item returned null netclass
- re-worked PNS_LINE_PLACER and PNS_ROUTER classes a bit, removing duplicate class members
- cleaned up Andrew's blind/buried via fixes
- fixed 'custom via width' dialog bug updating the width even when closed/cancelled
- fixed incorrect radius of drawn microvias
