Subject: tetraflexagon_diagram: do not use a fill_color for the template tiles
X-Git-Url: https://git.ao2.it/flexagon-toolkit.git/commitdiff_plain/fac262ce3b0cd8db67f15e43cc106acdf35a18bf?hp=6ed0df361ceb82dcd9fb592c910123a2d3a274ed

tetraflexagon_diagram: do not use a fill_color for the template tiles

Pass fill_color=None when drawing the template to make it only
a wireframe reference, as it is done for the hexaflexagon case.

This also makes the result more usable as the user is able to view the
content layers more clearly without filled squares on top.
