/**
 To improve the hinting of the fonts, this code uses a hack
 presented here:

 http://antigrain.com/research/font_rasterization/index.html

 The idea is to limit the effect of hinting in the x-direction, while
 preserving hinting in the y-direction.  Since freetype does not
 support this directly, the dpi in the x-direction is set higher than
 in the y-direction, which affects the hinting grid.  Then, a global
 transform is placed on the font to shrink it back to the desired
 size.  While it is a bit surprising that the dpi setting affects
 hinting, whereas the global transform does not, this is documented
 behavior of freetype, and therefore hopefully unlikely to change.
 The freetype 2 tutorial says:

      NOTE: The transformation is applied to every glyph that is
      loaded through FT_Load_Glyph and is completely independent of
      any hinting process. This means that you won't get the same
      results if you load a glyph at the size of 24 pixels, or a glyph
      at the size at 12 pixels scaled by 2 through a transform,
      because the hints will have been computed differently (except
      you have disabled hints).
