Wiping moves performed before moving away from the wipe tower were replaced by
scheduling a regular wipe that is performed after normal gcode generator regains
control. This makes it consistent with wipes on the model and gets rid of the
unretracted wipes.
1) Fixed a wrong offset when extracting infill lines from the octree.
2) Added a variant for testing triangle in a bounding sphere
when buildind the octree. Currently not used as the box test
is more tight.
3) "Bridging infill" regions are now triangulated and used to densify
the octree as well to support the bridging infill correctly.
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)
UnsavedChangesDialog: Disabled "Move changes to selected preset" button, when printer technology is changed
PresetComboBox: Fixed color of the filament, if it is modified
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.
* added "settings" and "search_blink" icons
* suppress the icons scaling update when Plater is in the Preview mode
* switched "layers_height" and "search" buttons in the toolbar
* Show it on the display same as an Application
* Code refactoring : All related functions moved to the SplashScreen class
* Add a possibility o hide/show splash scree in Preferences
