Adaptor - Handle font style correctly in the font controller.
[problem] The font controller always retrieves a 'Regular' font style if no font name is given,
even if a different font style is set (ex: Light) and a valid font for this style exists.
[cause] If no font name is given, the font controller resets the style to default (which is Regular) as well.
In general the font controller doesn't handle the font style completely.
[solution] Fix the handle on font styles inside the font controller.
