public interface Element

Interface for a text element.

Remark: I looked at the interface javax.swing.text.Element, but I decided to write my own text-classes for two reasons:

1. The javax.swing.text-classes may be very generic, I think they are overkill: they are to heavy for what they have to do.
2. A lot of people using iText (formerly known as rugPdf), still use JDK1.1.x. I try to keep the Java2 requirements limited to the Collection classes (I think they're really great). However, if I use the javax.swing.text classes, it will become very difficult to downgrade rugPdf.
