After some testing I'm getting the impression that the bokeh filter isn't
strictly applied. I'm getting square shapes when using a bokeh which is mostly
black, as if the algorithm gives up after a few tries and just uses the sample
anyway. Indeed, using a completely black bokeh filter doesn't cause any error
and I still have blur.
This is an understandable limitation of the bokeh filter implementation, but it
limits my ability to use it to randomize blur samples.
Anyway, for the time being I don't really need high quality focal blur in an
animation, and if I do I can just use more blur_samples to brute-force it. But
it would be nice if someone could take a look at the code to fix these niggles.
