m_dragstatus is set to true when a valid route is created given the
user's constraints. We need to check this before committing the route
to the board.
Fixes: lp:1794810
* https://bugs.launchpad.net/kicad/+bug/1794810
Previously, dragging changes were applied only if the last cursor move
finished with a successful drag operation. It made items squeezing
difficult, as it required accurate cursor movement to apply the changes.
add overloads for NODE::Add( ... ) taking pointers to specific item types (retain old private add-Functions, they will come in handy later)
LINE overloads now take by reference, to document their special treatment.
updated code throughout affected by these changes
- 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
