Collection of data from internal wipe tower gcode generator now uses move semantics.
Part of gcode at the end of priming was erroneously not exported (extruder current reset etc.)
+ Create controls only on the shown and active tab
+ Line class : deleted unused sizer
+ In GUI_Utils added TaskTimer class for the print a time of some task duration
+ BedShapeDialog:: activated options_groups
+ commented some unused code
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.
If an object indicates a valid timestamp, then the timestamp
is relied upon to not serialize the object data if the timestamp
of the same object on the undo/redo stack matches.
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
