I'm late to the party and this has already been partially addressed in the
thread, but it always annoys me. A square is as much a rhombus with 90
degree angles as it is a rectangle with equal length and width, and yet I
*never* see the former given as an option.

If course, that's probably because rectangles have a multitude of uses for
user interfaces, whilst other quadrilaterals are somewhat less useful.
