Here (and in other places) it would be great to have a function to format with a fixed number of significant digits. Does egui happen to already have this functionality somewhere?

Look at emath::round_to_decimals and you see why the old code was weird :)

In a future PR we could change these to return WidgetText instead, allowing users to color the output.
