21 Symbols, dimensions and constants pertaining to visual output.
23 This struct takes care of all kinds of symbols, dimensions and
24 constants. Most of them are related to the point-size of the fonts,
25 so therefore, the lookup table for symbols is also in here.
29 add support for multiple fontsizes
31 add support for other len->wid conversions.
33 Input_engraver should be in here.
