Most bevy_refactor examples/ui do not work

[bendavidsteel]

When I run:
cargo run --release --features="nannou/egui" --example simple_ui

I get

Finished `release` profile [optimized] target(s) in 0.33s

This is on ubuntu. I get the same errors for tune_colour and circle_packing, but inspector_ui works.

By the way, is it still likely that bevy_refactor will be merged? What is the current status of nannou? I'm keen to use it (as a previous processing/open frameworks user) FYI!
