foreground, fgcolor, colorForeground text colour, can be a name or RGB value.
background, bgcolorBackground text colour, can be a name or RGB value.
font_family, faceFont face name.
font_weight, weightNumeric value in 0..900 range or one of "ultralight", + "light", "normal" (all meaning non-bold), "bold", "ultrabold" + and "heavy" (all meaning bold).
font_style, styleEither "oblique" or "italic" (both with the same meaning) + or "normal".
sizeThe font size can be specified either as "smaller" or + "larger" relatively to the current font, as a CSS font size + name ("xx-small", "x-small", "small", "medium", "large", + "x-large" or "xx-large") or as a number giving font size in + 1024th parts of a point, i.e. 10240 for a 10pt font.
