New config field for switching the support interface pattern between
default (rectilinear for non-soluble interface, concentric for soluble interface),
explicit rectilinear and explicit concentric.
Also the config layer was reworked a bit to reduce some switch statements
on ConfigOptionEnum<> templates.
Fixes [Request] Add optional perimeter to raft #756
Fixes First support layer does not stick to bed #2101
New parameters raft_first_layer_density and raft_first_layer_expansion
to influence the 1st layer of raft or support.
Fixes Allow to disable raft under support structures. #3772
Fixes raft is larger than necessary #2568
Fixes Supports on the build plate should have a solid bottom interface for better adhesion #1165
Changed the 1st layer infill to rectilinear even for soluble materials.
Fixes first layer of support for multi filament support oddly spaced #1445
Fixes Full Soluble Materials interfacing into Models + Soluble material noise on Bed #684
When an island contains exactly one infill ExtrusionEntity, this extrusion was oriented to maximize travel distance from the end of the previous extrusion of perimeters instead of minimizing it.
Fixes Brim destroyed by support aka. Enable supports on top of brim #1156
Fixes Brim Priority/Support on Brim #713
Fixes Phantom Support columns interfere with brim #3396
Fixes false generation of brim when supports are used #3395
This is a work in progress, as the brim generator currently produces
different brim areas from what the support generator expects.
When projecting the horizontal or nearly horizontal support enforcers or blockers
into object layers, the projection may fall on a layer above or below the layer
where it should in case the nearly horizontal support enforcer or blocker
triangles are intersecting the slicing plane of one of the object layers.
Due to numerical issues, projection of the support blocker or
enforcer triangles may not fall to the same side of the slicing plane
as when slicing the object. To make the projection robust, horizontal triangles
are newly projected to both the layer below and above if they are close
to the object slicing plane.
1. DoubleSlider::Control : Update extruder colors before another updates for layers slider
2. GCodeViewer : Control count of extruders during the legend updating
The projection algorithm was originally made for custom supports, so vertical triangles
were not interesting. They are for seam. Instead of rewriting the algorithm and risking
more bugs, the edge case is detected and the triangle is tilted slightly.
