Function egui::gui_zoom::zoom_with_keyboard

pub(crate) fn zoom_with_keyboard(ctx: &Context)

Let the user scale the GUI (change Context::zoom_factor) by pressing Cmd+Plus, Cmd+Minus or Cmd+0, just like in a browser.

By default, crate::Context calls this function at the end of each frame, controllable by crate::Options::zoom_with_keyboard.
