* 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.
PAD_SHAPE_T and PAD_ATTR_T still have a double definition (new names and old names) to be sure python scripts are nor broken by the change.
PAD_DRILL_SHAPE_T does not have a double definition, because it is unlikely oblong holes are used in python scripts.
Double definitions will be removed in the (next) future.
* Adds a "Grid Reference Point" to the VRML export; this allows a user to specify the (X,Y) coordinate which will be the origin point on the output
* Adds a "Grid Reference Point" to the IDF export; this is similar in purpose to the corresponding VRML export feature.
* Replace module nomenclature with footprint for improved consistency.
* Replace abbreviations in control text.
* Replace exchange nomenclature with change.
* 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.
Rename eeschema/dialogs/dialog_sch_find.fbp to dialog_schematic_find_base.fbp, to be consistent with other dialogs.
Pcbnew run from the project manager: add menu Save Copy As..., which is the same command as Save As ... in stand alone mode, but with the constraints of a project (no cwd change, no board filename change, and keep project settings)
Text arrays can now use "%s" as a placeholder to be substituted with the array index.
Also expand menu options for move exact, arrays and duplicate.
Minor fixes for arrays - use proper unit parsing, add numbering start for circular arrays
Add circle radius indicator to array dialogue
* Improve VRML export dialog lay out.
* Make the OK button the default action in the export dialog.
* Make 3D model export work correctly and avoid redundant file copies.
* Fix embedded path separators in wrl files on windows.
* Fix absolute model file path creation in wrl files.
* Clean up VRML export code.
