* @par The context
|
|
* A document can provide different forms of information about textual representation
|
|
* of its contents. It can include information about positions of every character on the
|
|
* page, this is the best possibility.
|
|
*
|
|
* But also it can provide information only about positions of every word on the page (not the character).
|
|
* Furthermore it can provide information only about the position of the whole page's text on the page.
|
|
*
|
|
* Also some document types have glyphes - sets of characters rendered as one, so in search they should
|
|
* appear as a text but are only one character when drawn on screen. We need to allow this.
|
|
* @par The idea
|
|
* We need several
