(possibly fully) understand. Next is moving the 2nd triangle out of the
first model's only "strip" (mesh doesn't sound right for what it does)
and into a 2nd model's "strip" (I'm qouting because while it is called
a strip in this instance, I plan to keep it to only one triangle/trigon
in the example code, at least until I start loading models from file to
render. Btw I call triangles trigons in code because I mis-type triangle
as traingle a lot
