Can't: Not intended for the same use.

Wants a (void *) tag.
"makes pointer from integer without a cast"

Still needed for computing DEMUX_GET_TIME.

Managed by libvnc.

I assume then that demux_t->pf_demux() isn't called its own separate thread.

Problem is the framebuffer is built incrementally.
I've change the way it is handled, but ended with a block_Duplicate...

Thought also about overriding block pf_release to use a unique or dual
fb, but it wouldn't be able to synchronize writes and caching would
provide stalled screen.
