Blur selected images by a box filter of specified size (fast recursive implementation).

order can be { 0=smooth | 1=1st-derivative | 2=2nd-derivative }.
boundary_conditions can be { 0=dirichlet | 1=neumann | 2=periodic | 3=mirror }.
When specified, argument axes is a sequence of { x | y | z | c }.
Specifying one axis multiple times apply also the blur multiple times.

Default values:

order=0, boundary_conditions=1 and nb_iter=1.
