Detailed Description

Paint objects using this painter to compute an accurate bounding box.

The Object::bbox member function computes a bounding box useful for distance calculations and optimizations. To find a bounding box that is accurate for the actual drawn object, paint the object using a BBoxPainter, and retrieve the box with bbox.
