The projection algorithm was originally made for custom supports, so vertical triangles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.
Projection into a grid has been reworked to use the AGG rasterizer.
This fixes#5209 and #6067.
Also the raster is now being oversampled by maximum 8x8 samples
and the supports are only allowed to expand inside the cell.
This significantly reduces leakage of supports through object walls,
which fixes#5054.
When the avoid crossing perimeters was enabled, and the wipe was enabled, there were unnecessary travels in the opposite direction than the wipe travel.

Base type interfaces for soluble interface supports
At the moment soluble support material adhesion is weak due to sparse support layers under soluble support layers. I reported as issue #5823 with pictures, as well.
I modified two methods to the SupportMaterial Class including their headers.
The new methods add two base type interface layers to the support structure, in case the extruders are different and soluble support is choosen.
Since it is conditionally activated, it in general doesn't need a GUI input. But a GUI option number of base interface layers may enabled users to adapt this feature to their needs.
This is my second try to provide a pull request on this topic. Reset my fromer repository, because first I merged this and all other changes to my master and couldn't provide separate pull request anymore.
ModelObject::split() expects a non-NULL new_objects vector where it adds pointers to the new models resulting from the split.
But in the CLI case the caller does not care about this and passes NULL which causes a crash. To fix the crash we could pass
a dummy vector but it turns out that we actually have a use for the results because we should assign a unique name to each
new model the same way as the GUI does. These names show up as comments in the gcode so this change makes the gcode produced
by the GUI and the CLI more similar and diffable.
@lukasmatena has amended the original commit by @combolek (pull request #5991) in order to avoid code duplication
Adjustment of GUI/3DBed.cpp,hpp to use the more stable triangulation algoritm
derived from SGI glut.
Fix of an extremely slow bridging calculation, caused by an extremely
slow bridged area detection function, of which the results were never used.
Fixes "slicing fails or takes too long #5974"
