This is also not true.

Again, this is *incorrect information*. Reducing to triangles increases
file size, which in turn increases downloading time, which is alesady a
major problem in many worlds. It is definitely *not* "more efficient for
everyone" to use triangles!

Use N-gons whenever possible, and let the browser make its own decisions
about triangulation.
