title: Draw good circle with SDL that is not as pixelated
body: <p>I want to draw a circle.</p>
  <p>This is my code and my output (<code>SDL_SetRenderDrawHexColor</code> is my own function that gives hex and converts that to rgba and <code>SDL_SetRenderDrawColor</code>.)</p>

  <p>Why is my output some pixely? I use this algorithm in canvas(js) and that was good, but in SDL it's bad. I think pixels are big, is that true?</p>
  <p>(For some reason I can't use <code>SDL_gfx</code>.)</p>
