I think it is related to Java 2D Rectangle class; as Java 2D grew up 
(and got subclasses for double) we did not need it so much.

Keep your head up; and the questions coming; and we will be fine!

Note the page I linked to is the page I wrote after answering this 
question a couple times on the user list; if you ever catch me answering 
one of your question and *not* using a wiki page we have something new 
to document.

You may of noticed that "ReferencedEnvelope" is the very first class 
document specifically for gt-api ;-) It was the first non JTS / GeoAPI 
"concept" we needed to explain to people - you you are right on track 
for learning GeoTools.
- http://docs.codehaus.org/display/GEOTDOC/01+ReferencedEnvelope

(I added an entry for Envelope2D there as an example of one of the Java 
Rectangle classes).

Cheers,
Jody
