 {{{
 7.4.3.7 I, J
 The mandatory I and J request parameters are integers that indicate a
 point of interest on the map that was produced by the embedded GetMap
 request (the “map request part” described in 7.4.3.3). The point (I,J) is
 a point in the (i,j) space defined by the Map CS (see 6.7.2). Therefore:
 ⎯       the value of I shall be between 0 and the maximum value of the i
 axis; ⎯        the value of J shall be between 0 and the maximum value of
 the j axis; ⎯        the point I=0, J=0 indicates the pixel at the upper
 left corner of the map; ⎯   I increases to the right and J increases
 downward.
 The point (I,J) represents the centre of the indicated pixel. If the value
 of I or of J is invalid, the server shall issue a service exception (code
 = InvalidPoint).
