* globals that seem to hold info for the wndproc).
*
* FindText[AW]/ReplaceText[AW]
* The find/replace calls are passed a structure that is _not_ used
* internally. There is a local copy that holds the running info to
* be able to combine xxxA and xxxW calls. The passed pointer is
* returned upon sendmessage. Apps won't break this way when they rely
* on the original pointer. This will work as long as the sizes of
* FINDREPLACEA == FINDREPLACEW. The local copy will also prevent
* the app to see the wine-specific extra flags to distinguish between
* A/W and Find/Replace.
