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.

Follow-up to 00db3dc41973b88e6ce0
referencing the issues fixed by the above commits:
Fixes Allow to disable raft under support structures. #3772
Fixes Separate counts for floor and roof support interface layers #4288
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.

Fixes Don't cancel support enforcers with "don't support bridges" #5105
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.
To be able to retrieve that information from a generated grid alone.
To avoid the copying of input mesh (for scaling) when doing the hollowing
Also remove some unused stuff from OpenVDBUtils
This is more a workaround than a fix: Windows 10 3D model fixing API refuses
to load a zip64 encoded 3MF. We need to get in touch with Microsoft on that
issue, for now the 3MFs generated for the Windows 10 3D model fixing API
will be limited to 4GB. Saving a bigger 3MF will fail.
This always contains the actual print_z of the toolchange, while layer_z contains the print_z
of the print. The two differ in case that wipe tower without sparse layers is used.
Related to #3834.
WIP: MutablePolygon - linked list based polygon implementation
allowing rapid insertion and removal of points.
WIP: porting smooth_outward() from Cura.
Added check for visibility for all loaded presets.
Added notification about this action.
+ PresetComboBox: Fixed update() function for physical printers, when some of related presets are invisible.
PrintObjectBase::status_update_warnings called PrintBase::status_update_warnings, which in turn set
SlicingStatus flag to UPDATE_PRINT_STEP_WARNINGS (instead of UPDATE_PRINT_OBEJCT_STEP_WARNINGS) and
saved its own ObjectID. This led to spurious and hard to read thread-unsafe crashes.
When was set use_external_mp_once to true then after first calling the avoid crossing perimeters this flag was reset which cases that on the second call of the avoid crossing perimeters the travel move didn't process as external.
Reworked skirt generator to only generate skirt at non-empty layers
(layers that actually extruder object or support) and to respect minimum
layer height. Skirt generator stops at the first layer where those both
conditions cannot be met.
Disabled a suspicious piece of legacy code inherited from Slic3r,
which tries to fill in spots inside support interfaces. The code was
too aggressive and it was doing more harm than good.
New config field for switching the support interface pattern between
default (rectilinear for non-soluble interface, concentric for soluble interface),
explicit rectilinear and explicit concentric.
Also the config layer was reworked a bit to reduce some switch statements
on ConfigOptionEnum<> templates.
Fixes [Request] Add optional perimeter to raft #756
Fixes First support layer does not stick to bed #2101
New parameters raft_first_layer_density and raft_first_layer_expansion
to influence the 1st layer of raft or support.
Fixes Allow to disable raft under support structures. #3772
Fixes raft is larger than necessary #2568
Fixes Supports on the build plate should have a solid bottom interface for better adhesion #1165
Changed the 1st layer infill to rectilinear even for soluble materials.
Fixes first layer of support for multi filament support oddly spaced #1445
Fixes Full Soluble Materials interfacing into Models + Soluble material noise on Bed #684
When an island contains exactly one infill ExtrusionEntity, this extrusion was oriented to maximize travel distance from the end of the previous extrusion of perimeters instead of minimizing it.
Fixes Brim destroyed by support aka. Enable supports on top of brim #1156
Fixes Brim Priority/Support on Brim #713
Fixes Phantom Support columns interfere with brim #3396
Fixes false generation of brim when supports are used #3395
This is a work in progress, as the brim generator currently produces
different brim areas from what the support generator expects.
When projecting the horizontal or nearly horizontal support enforcers or blockers
into object layers, the projection may fall on a layer above or below the layer
where it should in case the nearly horizontal support enforcer or blocker
triangles are intersecting the slicing plane of one of the object layers.
Due to numerical issues, projection of the support blocker or
enforcer triangles may not fall to the same side of the slicing plane
as when slicing the object. To make the projection robust, horizontal triangles
are newly projected to both the layer below and above if they are close
to the object slicing plane.
