I have seen that a new word (bokeh) was added in focal_blur, but there
is no explanation. Can someone detaiiled this feature? Thank you.

From memory... so I might be wrong: the "jitter/blur" can have another
pattern than the saint-andrew cross(4) or the hexgrid of 7 / 19 / 37.
you might provide your own pattern of density for (0,0)to (1,1) square
(at z=0) which will provide the actual distribution of the rays used for
blur. The density is the grey-evaluation of the pattern.
It allows to generate your own ray-distribution (using a random
generator), with your own number of samples.
For instance, you could provide an horizontal white line on a black
background to have only an horizontal blurring.

Thank you for your explanations, I understand a little more how it work.

A common use would be to have the image of the diafragm of an actual
camera to simulate the real bokeh of that real camera.
