 			The hinting mode to use. This controls how aggressively glyph edges should be snapped to pixels when rasterizing the font. Depending on personal preference, you may prefer using one hinting mode over the other. Hinting modes other than [b]None[/b] are only effective if the font contains hinting data (see [member force_autohinter]).
 			[b]None:[/b] Smoothest appearance, which can make the font look blurry at small sizes.
 			[b]Light:[/b] Sharp result by snapping glyph edges to pixels on the Y axis only.
