> Hi devs
> 
> I'd like to announce the branch 'raster-pipes-2' in Radims repository 
> https://github.com/blazek/Quantum-GIS for testing.
> Radim did a great job in refactoring the process of reading / resampling 
> / reprojecting / displaying / modifying raster layers. Every step is now 
> a subclass of QgsRasterInterface, with the advantage that several steps 
> can be chained in a QgsRasterPipe. Like that, the raster functionality 
> is nicely separated into different classes and it is easy to add/remove 
> elements in the pipe. The iteration over the raster parts is controlled 
> by QgsRasterIterator (because for high-resolution prints or analysis on 
> large datasets, it is impossible to keep everything in memory at once).
> 
> Please report any issue you find in the branch to the developer mailing 
> list.
> 
> Besides the changes in code architecture, there is also a new feature in 
> the raster-pipes-2 branch. It is now possible to write through 
> QgsRasterDataProvider (currently only supported by the gdal provider). 
> There is a 'save as...' function also for rasters now (though it is not 
> 100% complete at the moment). There is the option to save a raster in 
> one file or in tiles (the tiles are then saved in one directory and vrt 
> / pyramides are automatically created. Very usefull for saving the 
> contents of a WMS layer).
