If one part configured color solubility, the generated color texture seam between the neighbor parts will be gradient filled using this part's color with the specified solubility.

Mesh layout and thickness adjustment are depend on base plane calculation. In this build, the base plane calculation could be limited to front plane, side plane, and so on, compare to without any limitation in previous implementation.
Currently, only support "Normal" and "Inversion" modes, "Normal" means normal mesh union, "Inversion" means mesh diff, it behaves like subtract itself from the previous mesh.
Many source file name and data type are prefixed by "skeleton" before, now all are refactored.
The class MeshResultContext represents the outcome of mesh generation before, now we have material, pose and animation, so we just rename it as Outcome.
