title: Set "scaling" factor with awesome window manager
body: <p>How can one set the scaling factor in awesome window manager of "clients" (= window)?</p>
  
  <p><code>xrandr</code> shows me, that I have a resolution of <code>2880x1800 59.99*+</code> But the frames of the browsers and others (e.g. where the titles of the tabs are shown) seem to have font size about 100px. How can I change to a smaller scaling?</p>
