Hinting is a path->path transformation process done before rasterization, 
so we can create paths using the hinted outlines.  However, the FreeType 
rasterizer is optimized to generate bitmaps for small outlines, so we'll 
probably use instead of the cairo one, although they should generate 
essentially identical results.
