-- The function renderer.font.load can accept an option table as a second optional argument.
-- It shoud be like the following:
--
-- {antialiasing= "grayscale", hinting = "full"}
--
-- The possible values for each option are:
-- - for antialiang: grayscale, subpixel
-- - for hinting: none, slight, full
--
-- The defaults values are antialiang subpixel and hinting slight for optimal visualization
-- on ordinary LCD monitor with RGB patterns.
--
-- On High DPI monitor or non RGB monitor you may consider using antialiang grayscale instead.
-- The antialising grayscale with full hinting is interesting for crisp font rendering.
