Continuously recalculate blur

[Myzel394]

Is your feature request related to a problem?

When you have a non-state related change (for example a live preview of the camera), the image seems to be frozen.

Describe the solution you'd like:

Add an option to continuously recalculate the blur. Maybe add a parameter recalculationInterval that can be a number and will force an update every ms. 0 would mean "off" in this case. recalculationInterval = 16 for example would mean an update every 16ms.

Describe alternatives you've considered:

As a workaround I was thinking of adding a state that updates itself in intervals and thus forces recalculation.
