|
|
* @devnote
|
|
* For level 2, at caret IMEs, the IME will draw a window directly over the text giving the
|
|
* impression that the text is being processed by the application--this is called pseudo inline.
|
|
* All UI is handled by the IME. This mode is currenlty bypassed in favor of level 3 true inline (TI);
|
|
* however, it would be trivial to allow a user preference to select this mode. Some IMEs may have
|
|
* a "special" UI, in which case level 3 TI is *NOT* used, necessitating level 2.
|
|
*
|
|
* For level 2, near caret IMEs, the IME will draw a very small and obvious window near the current
|
|
* caret position in the document. This currently occurs for PRC(?) and Taiwan.
|
|
* All UI is handled by the IME.
|
|
*
|
|
* For level 3, at caret IMEs, the composition string is drawn by the application, which is called
|
|
* true inline, bypassing the level 2 "composition window".
|
|
* Currently, we allow the IME to support all remaining UI *except* drawing of the composition string.
