[feature] getBoundingClientRect for any node

[lavrton]

Hi, guys. I am thinking about adding new method getBoundingClientRect that will return object with x, y, width and height properties. Also the method will take into account:

1. offset
2. shadow
3. stroke
4. scale
5. group

That will allow us:

1. easy getting width and height values for groups
2. much better default caching behaviour
3. One way to detect position and size of nodes. (for example {x,y} of circle is center, but {x,y} of rect is top left point)
4. more...

Any thoughts?

really great idea ! I had to deal with such a case in one of my projects. If you implement it, I will try it immediatly.
