blur_bloom
Arguments:
- _amplitude>=0,_ratio>=0,_nb_iter>=0,_blend_operator={ + | max | min },_kernel={ 0=deriche | 1=gaussian | 2=box | 3=triangle | 4=quadratic },_normalize_scales={ 0 | 1 },_axes
Description:
Apply a bloom filter that blend multiple blur filters of different radii,resulting in a larger but sharper glare than a simple blur.
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:
amplitude=1, ratio=2, nb_iter=5, blend_operator=+, kernel=1, normalize_scales=0 and axes=(all)
Example of use:
