Created by Jonathan Mace
The Textbox class is the base class for our own custom textboxes which implement
the snapping to sentences/paragraphs/sections. The two subclasses are:
Editable_Textbox - this is a textbox with full editing features
Readonly_Textbox - this textbox is not editable and will not respond to
drags.
