; Description:      Find the position of an image on the desktop
; Syntax:           _ImageSearchArea, _ImageSearch
; Parameter(s):
;                   $findImage - the image to locate on the desktop
;                   $tolerance - 0 for no tolerance (0-255). Needed when colors of
;                                image differ from desktop. e.g GIF
;                   $resultPosition - Set where the returned x,y location of the image is.
;                                     1 for centre of image, 0 for top left of image
;                   $x $y - Return the x and y location of the image
;                   $transparency - TRANSBLACK, TRANSWHITE or hex value (e.g. 0xffffff) of
;                                  the color to be used as transparency; can be omitted if
;                                  not needed
;
; Return Value(s):  On Success - Returns 1
;                   On Failure - Returns 0
;
; Note: Use _ImageSearch to search the entire desktop, _ImageSearchArea to specify
;       a desktop region to search
