this isn't actually a bug but the code is perhaps a little  
unnecessary.  The calculated variables indicate the size of a pixel  
in geographic units in the x and y directions.  Normally these are  
equal (pixels are square) although it is possible for pixels to be  
non-square.  If that is ever needed, then we would replace the code  
calculating these values with the appropriate calculation for each
