So the test result is: non-zero size for group caused problems when a transformation is applied to a group since the actual bouding rect of group changes with transformations being applied on the group and it's childrens. The easy way is to cancel transformation on group, and I think that's why group size has been explicitly set as 0. So I think we should keep the group as a simple 0-size stuff but provide a method to reflect it's current state, i.e. the non-zero returned boundingRect method.
