The problem was in the fallback code of the primitive. Characters don't 
allow #bitXor: anymore. Assuming they once did. I was not aware of that. 
I any case, why on Earth should Characters know about bitpatterns? Just 
fixed the PNG loader. Seems to work OK now.

Oh, yes! Celebrations here will last for several days!

Take a look: 
https://www.theguardian.com/world/video/2022/dec/19/drone-captures-sea-of-fans-celebrating-in-buenos-aires-after-argentinas-world-cup-win-video
People dancing on the top of traffic lights! Tens of people on the roof 
of the bus stop! Easily a million people on the streets. It was great!

If you enjoy soccer (Football would be the correct, English name of the 
game), watch the final. It was thrilling. Some of the best in the world, 
pushing full throttle every minute.

Cheers,
