* - Controls with SS_SIMPLE but without SS_NOPREFIX:
|
|
* The text should not be changed. Windows doesn't clear the
|
|
* client rectangle, so the new text must be larger than the old one.
|
|
* - The SS_RIGHTJUST style is currently not implemented by Windows
|
|
* (or it does something different than documented).
