A Text Box element lets us display word-wrapped, formatted text. If the text to display is longer than the height
of the box given then the element will automatically create a vertical scroll bar so that all the text can be seen.
Formatting the text is done via a subset of HTML tags. Currently supported tags are:
- <b></b> or <strong></strong> - to encase bold styled text.
- <i></i>, <em></em> or <var></var> - to encase italic styled text.
- <u></u> - to encase underlined text.
- <a href='id'></a> - to encase 'link' text that can be clicked on to generate events with the id given in href.
- <body bgcolor='#FFFFFF'></body> - to change the background colour of encased text.
- <br> - to start a new line.
- <font face='verdana' color='#000000' size=3.5></font> - To set the font, colour and size of encased text.
More may be added in the future if needed or frequently requested.
NOTE: if dimensions of the initial containing rect are set to -1 the text box will match the final dimension to
whatever the text rendering produces. This lets us make dynamically sized text boxes depending on their contents.
