How can I create a border of a specified width and color for a "triangle"
Finite_Patch Object having a different color? I tried "merge" and "union"
of two different-size triangle and that doesn't want to compute.
If this can't be done, what is the slickest way to create a thin equilateral
"Finite Solid" triangle having a border edge and different color than the
remainder of the triangle?
