Fixed a problem for shape repaint, where instead of the correctly transformed bound rect the original shape bounds where taken 2004/08/11 15:56:01 thb 1.1.2.1: Initial revision

This class wraps the plain Shape with a wrapper for subset

that the reason to have shape subsetting RAII implemented
|
|
separately (i.e. not within the DrawShape) was that

subsetting (and de-subsetting) needs the LayerManager. And

holding that at the DrawShape creates one heck of a

circular reference.
