yes, it would give you quite a complete overview of how I see that  
tool working,
I hope the site can be up soon.

meanwhile, try this google cache:
<http://209.85.135.132/search?q=cache:5vLW1Vm8rQIJ:gui.gimp.org/index.php/Transformation_tool_specification

however, last week I have updated the design of the shear and  
perspective
transform handles and all opcities:
<http://mmiworks.net/test/no%20parallel.png> and
<http://mmiworks.net/test/no%20parallel.jpg>

this of course triggers a big update of the spec. there are also some
rough edges in the spec that need to be defined: like when the frame is
partially in view, or no edge of the frame is in view.

btw: getting the opacity part working may need some serious grunt work.
ask the developers about it.

The new transform tool is indeed a combined transform tool: move,  
rotate,
scale, shear, perspective.

see my intro in the spec. but the short version is: the combined tool is
"to supersede the move, scale and shear tools" and should be  
complemented
by expert rotate and perspective tools. the flip tool is a goner.
