/*
Data structures
===============
Data is represented by a hierarchy of objects, all derived from
wxRichTextObject.
The top of the hierarchy is the buffer, a kind of wxRichTextParagraphLayoutBox.
These boxes will allow flexible placement of text boxes on a page, but
for now there is a single box representing the document, and this box is
a wxRichTextParagraphLayoutBox which contains further wxRichTextParagraph
objects, each of which can include text and images.
Each object maintains a range (start and end position) measured
from the start of the main parent box.
A paragraph object knows its range, and a text fragment knows its range
too. So, a character or image in a page has a position relative to the
start of the document, and a character in an embedded text box has
a position relative to that text box. For now, we will not be dealing with
embedded objects but it's something to bear in mind for later.
Note that internally, a range (5,5) represents a range of one character.
In the public wx[Rich]TextCtrl API, this would be passed to e.g. SetSelection
as (5,6). A paragraph with one character might have an internal range of (0, 1)
since the end of the paragraph takes up one position.
Layout
======
When Layout is called on an object, it is given a size which the object
must limit itself to, or one or more flexible directions (vertical
or horizontal). So for example a centered paragraph is given the page
width to play with (minus any margins), but can extend indefinitely
in the vertical direction. The implementation of Layout can then
cache the calculated size and position within the parent.
