title: SDL anti-aliasing without OpenGL?
body: <p>I'm trying to make a game in C++ using SDL.
  I would like to implement anti-aliasing in the graphics, but everything I have searched for online on the subject has suggested either an external library, or a solution that also involves OpenGL.</p>
  
  <p>Is there a way to do anti-alias without OpenGL (such as modifying the graphics before hand, or possibly some function that I didn't find)? If not, how hard is it to convert a game written in SDL to use OpenGL as well (I have not worked with OpenGL before...)?</p>
