TriangleSelector::valid refactored to m_valid and valid()
and bool members moved next to each other to shrink data structure
size due to memory alignment.
Changed the serialization structure
std::map<int, std::vector<bool>>
to a significantly more compact
std::pair<std::vector<std::pair<int, int>>, std::vector<bool>>
Such change shall significantly improve efficiency of Undo / Redo stack.
Serialization and deserialization in TriangleSelector were extended to support up to 16 materials (3 unused states left for possible later extension). These changes also affect the encoding of data from custom supports and seams, but it is backward compatible with the previous encoding. And for custom supports and seams, it is produced exactly the same data encoding as before.
- Extra dialog for autosetting by angle in FDM supports gizmo was removed
- Highlighting facets by angle is now controlled by a slider in the main gizmo dialog
- User is allowed to paint even when using the slope highlighter
- The button to turn highlighted facets to blockers was removed, it made no sense
- Highlighted facets are now rendered in light blue
