The exPreventOverlapMixt flag must always be used alongside either the exPreventOverlap or exChangeColorOnOverlap flag. When used with the exPreventOverlap flag, it ensures that links avoid overlapping with elements or obstacles, enabling their paths to include both rectangular and diagonal lines. When combined with the exChangeColorOnOverlap flag, overlapping links alternately adjust their width in addition to changing colors (sample 2)
