This helped me benchmark the atomic layout (#5830) changes. I also realized that the label benchmark wasn't testing the painting, since the buttons at some point will be placed outside the screen_rect, meaning it won't be painted. This fixes it by benching the label in a child ui. The `label &str` benchmark went from 483 ns to 535 ns with these changes. EDIT: I fixed another benchmark problem, since the benchmark would show the same widget millions of times for a single frame, the WidgetRects hashmap would get huge, causing each iteration to slow down a bit more and causing the benchmark to have unreliable results. With this the `label &str` benchmark went from 535ns to 298ns. Also the `label format!` benchmark now takes almost the same time (302 ns). Before, it was a lot slower since it reused the same Context which already had millions of widget ids.

egui demo library
This crate contains example code for egui.
The demo library is a separate crate for three reasons:
- To ensure it only uses the public
eguiapi. - To remove the amount of code in
eguiproper. - To make it easy for 3rd party egui integrations to use it for tests.
This crate also contains benchmarks for egui. Run them with
# Run all benchmarks
cargo bench -p egui_demo_lib
# Run a single benchmark
cargo bench -p egui_demo_lib "benchmark name"
# Profile benchmarks with cargo-flamegraph (--root flag is necessary for MacOS)
CARGO_PROFILE_BENCH_DEBUG=true cargo flamegraph --bench benchmark --root -p egui_demo_lib -- --bench "benchmark name"
# Profile with cargo-instruments
CARGO_PROFILE_BENCH_DEBUG=true cargo instruments --profile bench --bench benchmark -p egui_demo_lib -t time -- --bench "benchmark name"
