+% RES = blur(IM, LEVELS, FILT)
+%
+% Blur an image, by filtering and downsampling LEVELS times
+% (default=1), followed by upsampling and filtering LEVELS times.  The
+% blurring is done with filter kernel specified by FILT (default =
+% 'binom5'), which can be a string (to be passed to namedFilter), a
+% vector (applied separably as a 1D convolution kernel in X and Y), or
+% a matrix (applied as a 2D convolution kernel).  The downsampling is
+% always by 2 in each direction.
