-// Class outline_aa - implementation.
-//
-// Initially the rendering algorithm was designed by David Turner and the
-// other authors of the FreeType library - see the above notice. I nearly
-// created a similar renderer, but still I was far from David's work.
-// I completely redesigned the original code and adapted it for Anti-Grain
-// ideas. Two functions - render_line and render_hline are the core of
-// the algorithm - they calculate the exact coverage of each pixel cell
-// of the polygon. I left these functions almost as is, because there's
-// no way to improve the perfection - hats off to David and his group!
-//
-// All other code is very different from the original.
