Function TileHandler.DelaunayRefinement

int DelaunayRefinement (

UnsafeSpan<Int3>	verts
UnsafeSpan<int>	tris
UnsafeSpan<int>	tags
bool	delaunay
bool	colinear

)

Refine a mesh using delaunay refinement.

Loops through all pairs of neighbouring triangles and check if it would be better to flip the diagonal joining them using the delaunay criteria.

Does not require triangles to be clockwise, triangles will be checked for if they are clockwise and made clockwise if not. The resulting mesh will have all triangles clockwise.
