* 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
ModelObject::split() expects a non-NULL new_objects vector where it adds pointers to the new models resulting from the split.
But in the CLI case the caller does not care about this and passes NULL which causes a crash. To fix the crash we could pass
a dummy vector but it turns out that we actually have a use for the results because we should assign a unique name to each
new model the same way as the GUI does. These names show up as comments in the gcode so this change makes the gcode produced
by the GUI and the CLI more similar and diffable.
@lukasmatena has amended the original commit by @combolek (pull request #5991) in order to avoid code duplication
Fix of #5007 - "Reload from disk" causes objects converted to inches to revert to mm
1) Storing and reloading the "source_in_inches" source flag from AMF and 3MF
2) When converting objects with mixed "inches" volumes, do the right thing
and do not convert those that do not need conversion.
to help with detecting "not changed" event when taking
Undo/Redo snapshot or synchronizing with the back-end.
Converted layer height profile and supports / seam painted areas
to the same timestamp controlled structure.
1) Octree is built directly from the triangle mesh by checking
overlap of a triangle with an octree cell. This shall produce
a tighter octree with less dense cells.
2) The same method is used for both the adaptive / support cubic infill,
where for the support cubic infill the non-overhang triangles are
ignored.
The AABB tree is no more used.
3) Optimized extraction of continuous infill lines in O(1) instead of O(n^2)
1) All slicer's exceptions are now derived from Slic3r::Exception.
2) New exceptions are defined for slicing errors.
3) Exceptions are propagated to the Plater to show.
It remains to modify the slicing back-end to throw the new SlicingError
exceptions instead of std::runtime_error and to show the other exceptions
by a message dialog instead of a notification.
