Emil Ernerfeldt dc79998044 Improve text rendering in light mode (#7290 )

This changes how we convert glyph coverage to alpha (and ultimately a
color), but only in light mode.

This is a bit of a hack, because it doesn't fix dark-on-light text in
_dark mode_ (if you have any), but for the common case this PR is a huge
improvement.

You can also tweak this yourself now using
`Visuals::text_alpha_from_coverage` or from the UI (bottom of the
image):

## Black text Before/after
If you think the text above looks too weak, it's only because of the
default text color. Here's how it looks like with perfectly `#000000`
black text:

`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 egui api.
To remove the amount of code in egui proper.
To make it easy for 3rd party egui integrations to use it for tests.
- See for instance https://github.com/not-fl3/egui-miniquad/blob/master/examples/demo.rs

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"
