How to make an admin plugin menu page go full screen?

Per the comments, it doesn’t seem there is anything built in for this. I included this code in my page to hide the admin menus:

<style>
    #adminmenumain, #wpadminbar {
        display: none;
    }
</style>

You’ll have to muck about with CSS to get your page right. But it seems to work ok.
