; 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
