I don't think the type of these memory buffers is related to the type
of the values in your raster. They are probably fine.

You may have to look into the MorphESRIRasterDepth function to see
whether that needs to be updated. It probably needs to be in sync with
the MorphESRIRasterType function.

If that doesn't help than you may want to wait for other suggestions,
because I might be completely wrong. That has happened before ;-)
