double downscale() const;
%Docstring
Returns by how much the renderer will scale down the request to the data
provider. For example, for a raster block 1000x500 with downscale 10,
the renderer will request raster 100x50 from provider. Higher downscale
makes contour lines more simplified (at the expense of losing some
detail). The value of one means there will be no downscaling.
%End

%Docstring
Sets by how much the renderer will scale down the request to the data
provider.
