  36  * globals that seem to hold info for the wndproc).

  38  * FindText[AW]/ReplaceText[AW]
  39  * The find/replace calls are passed a structure that is _not_ used
  40  * internally. There is a local copy that holds the running info to
  41  * be able to combine xxxA and xxxW calls. The passed pointer is
  42  * returned upon sendmessage. Apps wont break this way when they rely
  43  * on the original pointer. This will work as long as the sizes of
  44  * FINDREPLACEA == FINDREPLACEW. The local copy will also prevent
  45  * the app to see the wine-specific extra flags to distinguish between
  46  * A/W and Find/Replace.
