Support light mode in the Rerun viewer

[edulecom]

Hello,

I'm playing with .\rerun\crates\re_ui\examples\re_ui_example.rs and I'm trying to change the theme to light.
I have added only one line in the fn update:

    egui::TopBottomPanel::bottom("bottom_panel")
        .frame(self.re_ui.bottom_panel_frame())
        .show_animated(egui_ctx, self.bottom_panel, |ui| {
            ui.strong("Bottom panel");
            egui::widgets::global_dark_light_mode_buttons(ui); // this line is added
        });  

Effect is strange: only central panel applies the theme. It can be seen in an attached video.
Any help would very appreciated.

The out of the box theme settings are bound to not work properly in rerun as we sadly change a lot of the theming colors in Rerun on-the-fly. At least I suspect that's what's most of the issue here.

That said, (re)adding a light mode is something we want to do eventually.
Are you just trying out things or is a Rerun light theme something you'd like to have as well?

Thank you for your response. I'm currently in the process of developing an app using re_ui, and while the absence of a light mode isn't a critical issue, having that feature would certainly be a welcome addition.
