...267    into fmbtgti.GUITestInterface instances and Screenshots.268    To implement an OCR engine, you need to override _findText() at269    minimum. See _findText documentation in this class for270    requirements.271    If possible in your OCR engine, you can provide _dumpOcr() to272    reveal what is recognized in screenshots.273    For efficient caching of results and freeing cached results, you274    can override _addScreenshot() and _removeScreenshot().

If663              scale is 1.0, default is 1 (rectangle is 1x1).
