expanded to a grid (the old way) vs.
snug (like the upstream Slic3r, Cura or Ideamaker).
Snug supports suffered from the degeneracies when merging overhang islands
over a large number of layers when projecting the support towers down.
We borrowed the idea & a bit of code from Cura by simplifying the support
polygons by closing the concave cracks, see the smooth_outward() function
and the MutablePolygon class.

1) If "support on build plate only" is enabled, the support columns are
newly trimmed to not land on top of an object. However this may make
the column too small to be stable.
2) Support enforcers newly take precedence over "supports on build plate only"
and over "don't support bridges".
3) Some refactoring of the support generator code for clarity: Reduced
some of the worst spagetti offenders.

were missing abruptly when going down.
The issue was caused by extracting support areas from a grid and
filtering the extracted islands by intersection with the input islands.
Sometimes the input islands were a bit bigger than the extracted contour,
thus some of the samples of the input islands did not fall into
the extracted contour.
the Chromebooks share their file system to Linux using the 9p file
system, which does not support setting file ownership. Newly PrusaSlicer
will detect platform and it will not panick if copy_file() cannot set
file ownership after copying. It just logs the incident, and on
chromebooks the loglevel for that incident is "Info", not "Error".
Adjusted the full screen mode to contain menu bar.
Moved Platform.cpp/hpp to libslic3r
* GUI_ObjectList code refactoring:
The MenuFactory structure contains functions related to the context menu and bitmaps used to different volume types.
The SettingsFactory structure contains functions to getting overridden options, its bundles and bitmaps used to setting categories.
Fixed bugs/crashes:
1. Add object -> Add Settings from 3D scene -> Right click on object => Part's Settings list instead of object's
(Same behavior if something else but Object is selected in ObjectList)
2. Add settings to the part -> Change part type to the "Support Blocker/Enforcer" -> Settings disappears (it's OK) but =>
Save Project -> Open project => Support Blocker/Enforcer has a settings
3. Add part for object -> Change type of part -> Change monitor DPI -> old type icon appears
4. Select all instances in ObjectList -> Context menu in 3D scene -> Add Settings -> Select some category -> Crash
* ObjectLayers: Fixed a crash on re-scaling, when some layer range is selected
* Fixed OSX build
* Added menu item "Split to Objects" for multipart objects
+ Fixed bug: Add 2 parts,
Add some settings for one part
Delete part without settings => Single part object without settings, but settings are applied for the object.
+ Next refactoring: use same menu for Plater and ObjectList
If the new support_material_bottom_interface_layers is left at default -1,
then support_material_interface_layers is used for both top and bottom
interface layers.
If support_material_interface_layers == 0, then neither top nor bottom
interface layers are being extruded.
