Now in order to implement this correctly we also need to take rtl languages and languages such as Thai into account to get line break opportunities computed.

java.awt.font.TextLayout can do this.

> The appearance handling for forms in 1.x is limited and does not reflect all settings possible for form fields. In addition the current code is not very modular and does not follow the box model used for form fields. 
> Unfortunately only the basics of form handling are defined in the PDF spec. The details like padding of boxes, text placement etc. have to be determined by looking at how Adobe forms are generated.
