-   *   This section contains technical definitions.
+   *   A raster or a rasterizer is a scan converter in charge of producing a
+   *   pixel coverage bitmap that can be used as an alpha channel when
+   *   compositing a glyph with a background.  FreeType comes with two
+   *   rasterizers: bilevel `raster1` and anti-aliased `smooth` are two
+   *   separate modules.  They are usually called from the high-level
+   *   @FT_Load_Glyph or @FT_Render_Glyph functions and produce the entire
+   *   coverage bitmap at once, while staying largely invisible to users.
+   *
+   *   Instead of working with complete coverage bitmaps, it is also possible
+   *   to intercept consecutive pixel runs on the same scanline with the same
+   *   coverage, called _spans_, and process them individually.  Only the
+   *   `smooth` rasterizer permits this when calling @FT_Outline_Render with
+   *   @FT_Raster_Params as described below.

+   *   Working with either complete bitmaps or spans it is important to think
+   *   of them as colorless coverage objects suitable as alpha channels to
+   *   blend arbitrary colors with a background.  For best results, it is
