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
30 split into "Input_paper_def" and Paper_def
32 add support for other len->wid conversions.
34 Input_engraver should be in here.
