+  Note that internally, a range (5,5) represents a range of one character.

   in the vertical direction. The implementation of Layout can then
   cache the calculated size and position within the parent.
 

-  Note that position and size should be calculated separately, because
-  for example inserting a paragraph may result in the following paragraphs
-  moving down, but not changing in size.
-
-  Need to determine how objects specify their position. Absolute coordinates,
-  or relative to last object? May be hard to determine that. So should probably
-  be in absolute coordinates, in which case we'll need a Move virtual function
-  that allows quick movement of all elements without layout.
-
-  Let's work through a simple example of layout. Say we're laying out
-  a document with the buffer as the top box, with a wxRichTextParagraphLayoutBox
-  inside that that consists of wxRichTextParagraph objects.
-
-  We're in a mode whereby changes of window size change the width of the
-  page (useful for text editors, as opposed to word processors). The
-  window width is 600.
-
-  We pass (600, -1) to the top-level Layout (i.e. restrict size in horizontal
-  direction only). The wxRichTextBuffer box doesn't currently have
-  well-defined layout behaviour so we simply assume it has one child
-  that fills its parent (later we can define sizer-like box layout behaviour).
-  So it passes the same dimensions to the child, which is a wxRichTextParagraphLayoutBox.
-  This then looks at each child in turn (wxRichTextParagraph) and determines
-  the size the paragraph will take up, setting the cached size, and
-  splitting the paragraph into lines.
-
-  When the layout for one paragraph returns, the next paragraph is
-  fed the position of the previous, so it can position itself.
-
-  Each time Layout is called, the cached list of lines for each paragraph
-  is recreated, since it can change for example if the parent object width
-  changes.
-
-  Reporting size
-  ==============
-
-  Each object can report its size for a given range. It's important that
-  it can report a partial size, so that wrapping can be implemented,
-  hit test calculations performed, etc. So GetRangeSize must be implemented
-  for each object.
