* Fixed update of a warning icon for multi-part object, when some part with errors was deleted
* Fixed a crash when selecting non-Object and non-Volume item (in get_mesh_errors_info() was missed check of the obj_idx)
+ Follow-up 1cc7b4ba97 - some code refactoring:
* fixed RepairedMeshErrors.merge()
* get_mesh_errors_count() renamed to get_repaired_errors_count()
Export Finished notification ejecting state.
Slicing began state in progress notification.
Timing of progress bar notifications. Progress indicator disappears instantly at 100%. While slicing goes into Slicing Finished without fade out.
Preventing of negative growth of slicing progress bar.
Slicing progress bar - Negative percent value means now No info rather than Canceled.
Hiding slicing progress at printer technology change.
* Check Unsaved changes (partially related to #5903)
+ Allow create new project when Plater is empty, but some of presets are modified (related to #5903)
+ When creating new project allow Keep or Discard modification from previous project
+ Added check of changes:
* before any load project (including DnD and "Load From Recent Projects")
* before preset updater
* when configuration is changing from the ConfigWizard
+ Dialog caption is added for each check
+ Create/Destroy ConfigWizard every time when it's called
* Check Unsaved changes: Next Improvements
+ For dialog "Save project changes" added a reason of saving and name of the current project (or "Untitled")
+ UnsavedChangesDialog: Headers are extended to better explain the reason
+ Preferences: Fixed tooltiops for "Always ask for unsaved changes when..."
+ Suppress "Remember my choice" checkbox for actions which are not frequently used
* Fixed behavior of the application when try to save changed project but "Cancel" button is selected in "Save file as..." dialog
* Check unsaved changes: Improvements for Config Wizard - Check all cases when presets should be updated
+ Fixed info line for Materials pages. Text of the info relates to the printer technology now
* Improved suggested name for a project when Application is closing
* Fixed Linux/OSX build warnings
+ Show 2 groups of errors: "Auto-repared" and "Remaning".
+ Use different icons for volumes with/without remaining errors
+ Fixed update of the ObjectList warnings icons after switch the color mode of a PrusaSlicer
+ Some code refactoring: Use same code for tooltips for "exclamation"-icon from an ObjectList and from a Sidebar->ObjectInfo
TriangleMesh newly only holds indexed_triangle_set and
TriangleMeshStats. TriangleMeshStats contains an excerpt of stl_stats.
TriangleMeshStats are updated when initializing with indexed_triangle_set.
Admesh triangle mesh fixing is newly only used when loading an STL.
AMF / 3MF / OBJ file formats are already indexed triangle sets, thus
they are no more converted to admesh stl_file format, nor fixed
through admesh repair machinery. When importing AMF / 3MF / OBJ files,
volume is calculated and if negative, all faces are flipped. Also
a bounding box and number of open edges is calculated.
Implemented its_number_of_patches(), its_num_open_edges()
Optimized its_split(), its_is_splittable() using a visitor pattern.
Reworked QHull integration into TriangleMesh:
1) Face normals were not right.
2) Indexed triangle set is newly emitted instead of duplicating
vertices for each face.
Fixed cut_mesh(): Orient the triangulated faces correctly.
