//   Section 3.2 of Specification 800 (Braille Books and Pamphlets) February 2008 reads as follows:
//     Size and Spacing
//     3.2.1	The nominal height of braille dots shall be 0.019 inches [0.48 mm] and shall be uniform within any given transcription.
//     3.2.2	The nominal base diameter of braille dots shall be 0.057 inches [1.44 mm].
//     3.2.3	Cell spacing of dots shall conform to the following:
//     3.2.3.1	The nominal distance from center to center of adjacent dots (horizontally or vertically, but not diagonally)
//              in the same cell shall be 0.092 inches [2.340 mm].
//     3.2.3.2	The nominal distance from center to center of corresponding dots in adjacent cells shall be 0.245 inches [6.2 mm].
//     3.2.4    The nominal line spacing of braille cells from center to center of nearest corresponding dots in adjacent lines shall
//              be 0.400 inches [1.000 cm].
