Reworked skirt generator to only generate skirt at non-empty layers
(layers that actually extruder object or support) and to respect minimum
layer height. Skirt generator stops at the first layer where those both
conditions cannot be met.
The projection algorithm was originally made for custom supports, so vertical triangles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.

Refactoring of EdgeGrid structure to support both closed and open lines.
Replaced all "unsigned long long" types with uint64_t.
These "new" types better communicate their meaning and they are
guaranteed to behave the same on all platforms & compilers.
(linear tapering of extrusion rate for the 1st spiral vase layer)
Linear tapering could only be implemented for relative extruder distances.
For absolute extruder distances, all the G1 Exxx in all spiral vase layers
would have to be adjusted, which is much more complex and risky to do now
before release.
above the solid infill. Should fix
first layer of vase (after bottom layers) is bulging (0.6nozzle, 0.4 layerhight) #3712
Adjust flow of the "second" layer in spiral vase mode #2795
Bounding boxes of polygons could overlap. Ask the AABB tree for all possible candidates.
Might be faster than searching for the closest triangle, that requires traversing the whole depth of the tree every time.
Fan speed will be ramped up linearly from zero at layer disable_fan_first_layers
to maximum at layer full_fan_speed_layer. full_fan_speed_layer will be
ignored if lower than disable_fan_first_layers, in which case
the fan will be running at maximum allowed speed at layer
disable_fan_first_layers + 1.;
WIP: The cooling PresetHints are likely not finalized yet.
The strategy for the avoid crossing perimeters algorithm has been redesigned. But external travels (travel between objects or supports) have not been solved yet. For these travels is used a direct path between two points.
Much of the code has been reworked, which leads to significant speedup compared to the previous implementation.
Also, several potential bugs have been fixed.
