Good point. A clean solution would probably mean to use only methods in 
QgsRasterDataProvider interface to read data and pass it to the external 
tools like that. Both raster providers and plugins for external 
analytical tools can be added dynamically, so the provider interface is 
a good way to have consistency.

At the moment, not even the QGIS native raster tools use the raster 
provider interface (they have been written before the raster provider 
redesign). Something that I need to change in the mid-term.
