Update egui to 0.33 #82

lucasmerlin · 2025-09-17T13:23:19Z

There were some breaking changes around font handling.
I also ran cargo update.

This should be merged after the update msrv PR.

Tests fail because of a failure to read the glyph_width 🤔.
This is where it fails:

fn width_body_space(ui: &Ui) -> f32 {
    let id = TextStyle::Body.resolve(ui.style());
    ui.fonts_mut(|f| f.glyph_width(&id, ' '))
}
