* When Pcbnew is launched in the stand alone mode with no board file command
line option, the project path is set to the current working directory. The
user may not have write access to the current working directory which would
cause the auto save to generate an error. If the user does not have write
access to the current working directory, set the path to a platform specific
temporary path that the user has write permission.
* When Pcbnew is launched in the stand alone mode with no board file command
line option, the default BOARD object has no file name. Set the file name
to "noname.kicad_pcb" to fix incorrect auto save file name and set the path
to the user's platform specific document folder.
* Delete orphaned auto save files when closing without saving due to broken
auto save file generation logic which prepended the file name with "$" rather
than "_autosave-".
* Fixes: lp:1596382
* Split and rewrite the preview window and canvas.
* Create a new class for handling the board information.
* Adds new render targets: openGL, legacy, and ray tracing.
* Render targets take full advantage of the new 3D plugins system and 3D cache
for a fast 3D model loading.
* Faster board loading.
* New OpenGL render is faster than the old one.
* New ray tracing render target with a post processing shader.
* Use of new 3D plugins (WRL, X3D, STEP and IGES) and 3D model caching.
* Preview of 3D model while browsing the file name.
* 3D preview of the footprint while adding / align 3D shapes.
* Render of 3D models according to attributes: Normal, Normal+Insert, Virtual.
* Pivot rotation centered in one point over the PCB board.
* Shortcuts keys improved for XYZ orientation..
* Animated camera.
* Switched hashtables.h over to std::undordered_map from boost version.
* Added new macros DECL_VEC_FOR_SWIG() and DECL_MAP_FOR_SWIG() in macros.h.
These along with future DECL_HASH_FOR_SWIG() unify the declaration to swig
and C++ so that the resultant type name is common in both languages, and
the types AGREE.
* Fixed swigging of NETINFO_ITEM and NETINFO_LIST via magic.
* Newly exposed (python wrapped) are: D_PADS, TRACKS (was TRACK_PTRS),
NETNAME_MAP, NETCODE_MAP, wxString (without constructor purposely, read
comment in wx.i), MARKERS, ZONE_CONTAINERS, NETCLASSPTR, KICAD_T types.
* std::vector<SOMETHING*> tends to end up named SOMETHINGS in C++ and python.
Having the name consistent between like types is helpful, and between
languages. std::map<> ends up as SOMETHING_MAP.
* NETINFO_LIST::m_netNames and NETINFO_LIST::m_netCodes are now std::map
instead of hashtables, because swig does not yet support std::unordered_map.
* You can now get to any netclass or net info. NETNAMES_MAP and NETCODES_MAP
are traversable basically the same as a python dictionary using a python
string (not wsString) as the key! The wxString typemap converts python
string to wxString before the lookup happens. Iteration also works.
