sNominalPointSize (SHORT)
For a bit-map font, this field contains the height of the font.
For an outline font, this field contains the height intended by the font designer. For example, some fonts are designed for text use in which case a value of 120 (12 point) would probably be placed in this field, whereas other fonts are designed for "display" use ("display" is typographer's terminology for larger sizes). This is not the only size at which the font can be used.
Measured in decipoints (a decipoint is 1/720th of an inch).
