title: SDL2 texture repeat / wrapping property
body: <p>I want to use texture repeat with SDL2 (SDL_RenderCopy), and couldn't find how.
  by texture repeat I mean to give texture coords twice the size of the texture and have it tiled twice over the surface. like this: <a href="http://www.felixgers.de/teaching/jogl/textureClamp.html" rel="nofollow">http://www.felixgers.de/teaching/jogl/textureClamp.html</a></p>
  
  <p>anyone knows how to do it in SDL? do I need to access openGL functions myself?</p>
  
  <p>thanks,</p>
