* Code refactoring: get_connector_mesh() and apply_cut_connectors() moved from ModelObject to CutGizmo.
* Allow to change values of space and bulges for snaps
* cut_id for cut object is updated from attributes before all manipulations with perform a cut
* synchronization of the cut_id for whole model is execute now after all manipulations, related to the cut
Reworked handling of approximate / snug bounding boxes
at Model / ModelObject / PrintObject
Further optimized, so that the bounding boxes are not recalculated
unnecesarilly.
at Model / ModelObject / PrintObject
Fixes#9467#9519#9646
Also fixed variable layer height editing for case such as mentioned
in the github issues above.
Also likely fixed some of the sinking objects issues.
* Disable "Add/Edit connectors" button then cut to parts
* Fixed flip_cut_plane()
* Fixed cut by Line, when draw line over the cut plane
* Fixed apply of the transformations, when cut to parts
Cut improvements:
* Process "Ctrl"
* Change color of the cut plane when it's hovered
* Don't apply Cut information for result object(s), if cut doesn't have any connector or is cut to parts
(partially related to #9633 - Add option to Invalidate Cut Info at the time of cutting)
+ Rework CutDialog
+ Added "Cut to" section (Idea from #9564[Cut: Keep results as parts of current idea] was used, but there is other implementation)
+ Fix for #9657 - Inconvenient gizma, blocks the view of the cut of small parts
+ Add functionality "Flip cut plane" = Fix for #9632 - Adding connectors to either split cut part
+ ImGuiWrapper: added tooltip for button
Organic supports are not compatible.
Fixes#9528 and similar.
Moved the object max Z against build volume Z to Print::validate().
Updated layer_height_profile_from_ranges() to compress the resulting
ranges.
When try to delete something from the cut object, than not just inform the users about an impossibility of this action,
but allow them to invalidate a cut information or delete all connectors from related objects, but leave the cut info.
* CutGizmo: Fixed a label scale
* Fixed deselection of selected connectors, when moving the camera
* Implemented update of the settings for selected connectors
* Connector selection: Ctrl shortcut is changed to Shift to compatibility of the selection/deselection with rectangle selection
