Left, top right642              and bottom are either absolute coordinates (integers) or643              floats in range [0.0, 1.0]. In the latter case they are644              scaled to screenshot dimensions. The default is (0.0,645              0.0, 1.0, 1.0), that is, search everywhere in the646              screenshot.647      limit (integer, optional):648              number of returned matches is limited to the limit. The649              default is -1: all matches are returned. Applicable in650              findItemsByBitmap.651      allowOverlap (boolean, optional):652              allow returned icons to overlap. If False, returned list653              contains only non-overlapping bounding boxes. The654              default is False.655      scale (float or pair of floats, optional):656              scale to be applied to the bitmap before657              matching. Single float is a factor for both X and Y658              axis, pair of floats is (xScale, yScale). The default is659              1.0.660      bitmapPixelSize (integer, optional):661              size of pixel rectangle on bitmap for which there must662              be same color on corresponding screenshot rectangle.  If663              scale is 1.0, default is 1 (rectangle is 1x1). If scale664              != 1.0, the default is 2 (rectangle is 2x2).665      screenshotPixelSize (integer, optional):666              size of pixel rectangle on screenshot in which there667              must be a same color pixel as in the corresponding668              rectangle on bitmap.
