Segment Font

The pure core of a segment display: David Madison's ASCII mask tables for 7, 14 and 16 segments, plus the polygons that draw them. Bars are built from four numbers (width, height, thickness, gap) as mitred hexagons that meet at a gutter, diagonals are the thinner quads real glass has, and the italic lean is sheared about the baseline so the geometry and its bounding box agree. Reading a string is where the small real behaviours live — a decimal point rides the cell before it, overflow eats the end the text is not aligned to — and litRatio reports the duty cycle the panel's glow spills in proportion to.
