title: Anti-aliased Arc Pygame
body: <p>I am trying to code a simple circle timer in Python using Pygame. 
  At the moment it looks like this:
  <a href="https://i.stack.imgur.com/pjpXr.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/pjpXr.gif" alt="Timer"></a></p>
  
  <p>As you can see, the blue line is very wavy and has white dots in it. I am achieving this blue line by using pygame.draw.arc() function, but it is not anti-aliased and looks bad. I would like it to be anti-aliased, but gfxdraw module which should let me achieve this, doesn't support arc width selection. Here's code snippet:</p>
  
  <pre><code>pygame.draw.arc(screen, blue, [center[0] - 120, center[1] - 120, 240, 240], pi/2, pi/2+pi*i*koef, 15)
  pygame.gfxdraw.aacircle(screen, center[0], center[1], 105, black)
  pygame.gfxdraw.aacircle(screen, center[0], center[1], 120, black)
  </code></pre>
