The Preprogram Table
The preprogram table, with a tag name of'prep', is an optional table that stores the control value program. This is a set of outline font instructions that the Font Manager executes before it creates any glyph and again whenever the user changes the point size, the angle at which the font is being displayed, or the font itself. This table consists of an ordered list of instruction opcodes, each of which is one byte long. Control values for the instructions in the preprogram are found in the'cvt 'table, which is described in "The Control-Value Table" on page 4-73.
