 * @subsection Evas_Object_Textblock_Internal Internal Textblock Object Tutorial
 *
 * This explains the internal design of the Evas Textblock Object, it's assumed
 * that the reader of this section has already read @ref Evas_Object_Textblock_Tutorial "Textblock's usage docs.".
 *
 * @subsection textblock_internal_intro Introduction
 * There are two main parts to the textblock object, the first being the node
 * system, and the second being the layout system. The former is just an
 * internal representation of the markup text, while the latter is the internal
 * visual representation of the text (i.e positioning, sizing, fonts and etc).
 *
 * @subsection textblock_nodes The Nodes system
 * The nodes mechanism consists of two main data types:
 * ::Evas_Object_Textblock_Node_Text and ::Evas_Object_Textblock_Node_Format
 * the former is for Text nodes and the latter is for format nodes.
 * There's always at least one text node, even if there are only formats.
 *
 * @subsection textblock_nodes_text Text nodes
 * Each text node is essentially a paragraph, it includes an @ref Eina_UStrbuf
 * that stores the actual paragraph text, a utf8 string to store the paragraph
 * text in utf8 (which is not used internally at all), A pointer to it's
 * main @ref textblock_nodes_format_internal "Format Node" and the paragraph's
 * @ref evas_bidi_props "BiDi properties". The pointer to the format node may be
 * NULL if there's no format node anywhere before the end of the text node,
 * not even in previous text nodes. If not NULL, it points to the first format
 * node pointing to text inside of the text node, or if there is none, it points
 * to the previous's text nodes format node. Each paragraph has a format node
 * representing a paragraph separator pointing to it's last position except
 * for the last paragraph, which has no such constraint. This constraint
 * happens because text nodes are paragraphs and paragraphs are delimited by
 * paragraph separators.
 *
 * @subsection textblock_nodes_format_internal Format Nodes - Internal
 * Each format node stores a group of format information, for example the
 * markup: \<font=Vera,Kochi font_size=10 align=left\> will all be inserted
 * inside the same format node, although it consists of different formatting
 * commands.
 * Each node has a pointer to it's text node, this pointer is NEVER NULL, even
 * if there's only one format, and no text, a text node is created. Each format
 * node includes an offset from the last format node of the same text node. For
 * example, the markup "0<b>12</b>" will create two format nodes, the first
 * having an offset of 1 and the second an offset of 2. Each format node also
 * includes a @ref Eina_Strbuf that includes the textual representation of the
 * format, and a boolean stating if the format is a visible format or not, see
 * @ref textblock_nodes_format_visible
 *
 * @subsection textblock_nodes_format_visible Visible Format Nodes
 * There are two types of format nodes, visible and invisible. They are the same
 * in every way, except for the representation in the text node. While invisible
 * format nodes have no representation in the text node, the visible ones do.
 * The Uniceode object replacement character (0xFFFC) is inserted to every place
 * a visible format node points to. This makes it very easy to treat visible
 * formats as items in the text, both for BiDi purposes and cursor handling
 * purposes.
 * Here are a few example visible an invisible formats:
 * Visible: newline char, tab, paragraph separator and an embedded item.
 * Invisible: setting the color, font or alignment of the text.
 *
 * @subsection textblock_layout The layout system
 * @todo write @ref textblock_layout

 * All text items that intersect this block will be cut: the edge items (ones
