CREATESCALING Create the 3*3 matrix of a scaling in 2 dimensions.

   TRANS = createScaling(SX, SY);
   return the matrix corresponding to scaling by SX and SY in the 2
   main directions.
   The returned matrix has the form:
   [SX  0  0]
   [0  SY  0]
   [0   0  1]

   TRANS = createScaling(SX);
   Assume SX and SY are equals.

   TRANS = createScaling(CENTER, ...);
   Specifies the center of the scaling transform. The argument CENTER
   should be a 1-by-2 array representing coordinates of center.
