-/*
- * The picture_data class was designed with three primary goals:
- *
- * (i) Encapsulate state data formerly scattered (and inconsistently
- * structured) through multiple files,
- *
- * (ii) Provide some of the flexibility of building a scene in memory
- * instead of writing data immediately to the output,
- *
- * (iii) Ensure compatibility with existing syntax.
- *
- * A picture_data comprises two screens (canvas -- the bounding_box, and
- * page -- the picture box), unitlength and offsets, state data
- * (clip_box; angle units; styles for labels, painting, and arrowheads),
- * and a set of colors so that color dclarations in the output file can
- * be made using named colors.
- *
- * Dozens of global and member functions need to access and modify
- * the_picture(). Instead of making these functions friends, our data
- * (except for the color pallet) are public. Under the circumstances,
- * this seemed the Path of Least Evil.
