Blur effect on live scene?

[Michael Hoffer]

Hi Mike,

I have to agree with Tobias. While the effect works live (that was the
whole point of my demo video) it still does a lot of unnecessary copying
between CPU and GPU. OpenGL works without that. It doesn't have to transfer
data between CPU and GPU for each and every pulse.

Unfortunately, I didn't find another way without using private API or
patching OpenJFX. Ideas welcome :)

Regards,
Michael
