* 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.
* The board ratsnest visibility state was being saved in both the board file
and the Pcbnew configuration files causing visibility state issues. Use the
board file to save the board ratsnest visibility state.
* Remove all of the board ratsnest save visibility state to configuration file
code.
* Add code to set the board modified property when layer visibility states
change to give the user a chance to save the state in the board file.
* Some minor code cleaning and coding policy fixes.
* Create new dialog to edit environment variables.
* Add helper class ENV_VAR_ITEM to manage environment variable values and
if they were defined externally.
* A path configuration dialog access to KiCad, CvPcb, Pcbnew, and Footprint Editor
window menus.
* Add validator for environment variables.
