/**
|
||
|
|
* This defines all of the TextProperties structures that might be referenced
|
||
|
|
* by name from an embedded text string.
|
||
|
|
*
|
||
|
|
* A text string, as rendered by a TextNode, can contain embedded references
|
||
|
|
* to one of the TextProperties defined here, by enclosing the name between \1
|
||
|
|
* (ASCII 0x01) characters; this causes a "push" to the named state. All text
|
||
|
|
* following the closing \1 character will then be rendered in the new state.
|
||
|
|
* The next \2 (ASCII 0x02) character will then restore the previous state for
|
||
|
|
* subsequent text.
|
||
|
|
*
|
||
|
|
* For instance, "x\1up\1n\2 + y" indicates that the character "x" will be
|
||
|
|
* rendered in the normal state, the character "n" will be rendered in the
|
||
|
|
* "up" state, and then " + y" will be rendered in the normal state again.
|
||
|
|
*
|
||
|
|
* This can also be used to define arbitrary models that can serve as embedded
|
||
|
|
* graphic images in a text paragraph. This works similarly; the convention
|
||
|
|
* is to create a TextGraphic that describes the graphic image, and then
|
||
|
|
* associate it here via the set_graphic() call. Then "\5name\5" will embed
|
||
|
|
* the named graphic.
