export to raster formats - data sets skewed

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Export a data set with negative coord values and a cell size of 0.0833

What is the expected output? What do you see instead?
The results are skewed and do not plot correctly.  

This is likely related to issue #173

The root cause is that the prediction of the number of rows/cols is incorrect 
for some conditions.  The solution is to count the cols and rows as the system 
iterates over the X and Y coords.  This is how it is done in write_table_ers, 
which does not suffer from the issue.

This issue was updated by revision r947.

Calculating row and column counts using the same loop structures as when we 
iterate over the data.  
Doesn't match for export_ers, but that sub works as-is.
