43/* aaaaargh (pirate voice) ... notes!
44 *
45 * we have a big problem until now that's gone undetected... until yesterday.
46 * that problem involves clips and maps and smart objects. hooray! 3 of the
47 * more complex bits of evas - and maps and smart objects being one of the
48 * nastiest ones.
49 *
50 * what is the problem? when a clip crosses a map boundary. that is to say
51 * that when the clipper and clippee are not within the child tree of the
52 * mapped object. in this case "bad stuff" happens. basically as clips are
53 * then used to render objects, but they no longer apply as you'd expect as
54 * the map transfomr the objects to-be-clipped separately from the objects
55 * that clip them and this whole relationship is broken by maps. it somehow
56 * managed to not break with the advent of smart objects. lucky me... but
57 * maps killed it. now... what do we do? that is a good question. detect
58 * such a broken link and "turn off clipping" in that event - sure. but this
59 * isn't going to be cheap as ANY addition or deletion of a map to an object
60 * or any change in clipper of an object or any change in smart object
61 * membership needs to walk the obj tree both up and down from the changed
62 * object and probably walk entire object trees to find these and mark them.
63 * thats silly-expensive and i was about to fix it that way but it has since
64 * dawned on me that that is just going to kill performance in some critical
65 * areas like during object setup and manipulation, as well as teardown.
66 *
67 * aaaaagh! best for now is to document this as a "don't do it damnit!" thing
68 * and have the apps avoid it. but even then - how to do this? this is not
69 * easy. everywhere i turn so far i come up to either expensive operations,
70 * breaks in logic, or nasty re-work of apps or4 the whole concept of clipping,
71 * smart objects and maps... and that will have to wait for evas 2.0
72 *
73 * the below does clip fixups etc. in the even a clip spans a map boundary.
74 * not pretty, but necessary.

2 * @internal
3 * @section Evas_Object_Textblock_Internal Internal Textblock Object Tutorial
4 *
5 * This explains the internal design of the Evas Textblock Object, it's assumed
6 * that the reader of this section has already read @ref Evas_Object_Textblock_Tutorial "Textblock's usage docs.".
7 *
8 * @subsection textblock_internal_intro Introduction
9 * There are two main parts to the textblock object, the first being the node
10 * system, and the second being the layout system. The former is just an
11 * internal representation of the markup text, while the latter is the internal
12 * visual representation of the text (i.e positioning, sizing, fonts and etc).
13 *
14 * @subsection textblock_nodes The Nodes system
15 * The nodes mechanism consists of two main data types:
16 * ::Evas_Object_Textblock_Node_Text and ::Evas_Object_Textblock_Node_Format
17 * the former is for Text nodes and the latter is for format nodes.
18 * There's always at least one text node, even if there are only formats.
19 *
20 * @subsection textblock_nodes_text Text nodes
21 * Each text node is essentially a paragraph, it includes an @ref Eina_UStrbuf
22 * that stores the actual paragraph text, a utf8 string to store the paragraph
23 * text in utf8 (which is not used internally at all), A pointer to it's
24 * main @ref textblock_nodes_format_internal "Format Node" and the paragraph's
25 * @ref evas_bidi_props "BiDi properties". The pointer to the format node may be
26 * NULL if there's no format node anywhere before the end of the text node,
27 * not even in previous text nodes. If not NULL, it points to the first format
28 * node pointing to text inside of the text node, or if there is none, it points
29 * to the previous's text nodes format node. Each paragraph has a format node
30 * representing a paragraph separator pointing to it's last position except
31 * for the last paragraph, which has no such constraint. This constraint
32 * happens because text nodes are paragraphs and paragraphs are delimited by
33 * paragraph separators.
34 *
35 * @subsection textblock_nodes_format_internal Format Nodes - Internal
36 * Each format node stores a group of format information, for example the
37 * markup: \<font=Vera,Kochi font_size=10 align=left\> will all be inserted
38 * inside the same format node, altohugh it consists of different formatting
39 * commands.
40 * Each node has a pointer to it's text node, this pointer is NEVER NULL, even
41 * if there's only one format, and no text, a text node is created. Each format
42 * node includes an offset from the last format node of the same text node. For
43 * example, the markup "0<b>12</b>" will create two format nodes, the first
44 * having an offset of 1 and the second an offset of 2. Each format node also
45 * includes a @ref Eina_Strbuf that includes the textual representation of the
46 * format, and a boolean stating if the format is a visible format or not, see
47 * @ref textblock_nodes_format_visible
48 *
49 * @subsection textblock_nodes_format_visible Visible Format Nodes
50 * There are two types of format nodes, visible and invisible. They are the same
51 * in every way, except for the representation in the text node. While invisible
52 * format nodes have no representation in the text node, the visible ones do.
53 * The Uniceode object replacement character (0xFFFC) is inserted to every place
54 * a visible format node points to. This makes it very easy to treat visible
55 * formats as items in the text, both for BiDi purposes and cursor handling
56 * purposes.
57 * Here are a few example visible an invisible formats:
58 * Visible: newline char, tab, paragraph separator and an embedded item.
59 * Invisible: setting the color, font or alignment of the text.
60 *
61 * @subsection textblock_layout The layout system
62 * @todo write @ref textblock_layout
