title: Good algorithm for drawing solid 2-dimensional polygons?
body: <p>What is the simplest (and easiest, although that's subjective) algorithm for drawing solid (as in a single, solid color--no texture mapping) 2D polygons in memory?  What is the most efficient method?</p>
  
  <p>I am not interested in using the GPU or any rendering method, as the output of my program will not be to the screen.</p>
