Slicing algorithm
Algorithm used to slice the geometry:

-Auto: let IceSL decide the best algorithm for
the given geometry.

-Discrete: robust method, performs well on highly
detailed shapes, can slice anything (STLs,
implicits, voxels), performance depends heavily on
GPU specs and object XY extent. Method of choice
for complex models.

-Polygonal: limited to meshes with no defects,
does not depend on GPU specs, performs well
regardless of object XY extent, demanding on
high polygon counts. Method of choice when slicing
a single STL.
