The problem with simple deleting VIEW_ITEM_DATA upon VIEW_ITEM removal was
caused by the default copy constructors that copied pointers.
Once a copy of an item was destroyed, the VIEW_ITEM_DATA has been
destroyed, effectively invalidating m_viewPrivData for the other item.
- Finalize transition to BOARD_COMMIT (removed all remaining uses of PICKED_ITEMS_LIST) and implicit view/ratsnest updates
- Simplified SELECTION class, it now can be directly added to a VIEW
- Removed unnecesary casts and templates
- Introduced C++11 features (range based for, lambdas) where they improve code readability
- Added non-undoable COMMITs, which can be used to propagate change notifications to interested listeners (e.g. ratsnest/view)
2) Change from legacy Cu stack to counting down from top=(F_Cu or 0).
The old Cu stack required knowing the count of Cu layers to make
sense of the layer number when converting to many exported file types.
The new Cu stack is more commonly used, although ours still gives
B_Cu a fixed number.
3) Introduce class LSET and enum LAYER_ID.
4) Change *.kicad_pcb file format version to 4 from 3.
5) Change fixed names Inner1_Cu-Inner14_Cu to In1_Cu-In30_Cu and their
meanings are typically flipped.
6) Moved the #define LAYER_N_* stuff into legacy_plugin.cpp where they
can die a quiet death, and switch to enum LAYER_ID symbols throughout.
7) Removed the LEGACY_PLUGIN::Save() and FootprintSave() functions.
You will need to convert to the format immediately, *.kicad_pcb and
*.kicad_mod (=pretty) since legacy format was never going to know
about 32 Cu layers and additional technical layers and the reversed Cu
stack.
- SEGVIA becomes VIA
- Drill size moved from TRACK to VIA
- Removed shape from TRACK, becomes ViaType in VIA
- GetTrace becomes GetTrack, for uniformity
- Some minor constification and typo fixes
