title: Proper approach to program icon resolutions (Tkinter)
body: <p>I am developing a python program with tk based gui. I've found several issues with icons. I have company logo (512x512) and I want to make it application icon, which works ( window topbar icon, alt-tab icon, ...) - in addtional, on windows taskbar remains default. What's the problem is that, however I scale the image, I've tried several sizes, the alt-tab icon is always blurry and ugly. </p>
  
  <p>The application is not supposed to be installed (just clone and run), so I can't put several icons to /usr/share/icons (or can I?).</p>
  
  <p>To be specific:</p>
  
  <pre><code>root = tkinter.Tk()
  img = tkinter.PhotoImage(file='include/images/sp.gif')
  root.tk.call('wm', 'iconphoto', root._w, img)
  </code></pre>
  
  <p>Is there any way to solve this problem without application being installed? I've never done such thing before so thank you for any advice.</p>
