Detailed Description

This class calculates the bounding box of the object being drawn.

It can be used when doing the layout of the object in order to manage object spacing. The drawing primitives do not draw anything but update the bounding box values of the layout objects currently drawn. The layout objects store their own bounding box and a bounding box of their content. The own bounding box is updated only for the object being drawn (the top one on the stack). The content bounding box is updated for all objects on the stack
