[etoys-dev] Camera in e-toys/scratch

[karl ramberg]

Yes, I really chopped it down to the bare essentials.
All recording to holders must be built with tiles, not happen behind the scene.
No effects.
No multiple camera.
There are only a few tiles left for Etoy use, which  I think it really
covers most use anyway,
