IMO it is not a good idea to use Inf's or such as no data values
since comparisons of floating point values are non-reliable. I've
hit this in the case where I set raster data from GDAL raster to a
piddle in PDL (comparable to NumPy in Python world) for raster
algebra. I didn't find a good solution then - I'll need to examine
this changeset more and see if it provides a good solution to the
problem.<br>

Thanks,<br>
