I tried to create a rectangle and just assumed the type parameter would be "rectangle", but nothing appeared. I looked at the documentation and saw that it was "rect" instead of "rectangle". Once I
updated the code, everything worked great. But, it wasn't intuitive enough as I would have hoped on first attempt.

At a minimum, I would like to see "rectangle" also be supported and just alias to the "rect" type.
Optimally though, I'd like to see the type be changed to "rectangle", and "rect" be supported for backwards compatibility.
