The integers in Table 8-5 are derived by packing font family, face, and size
information into a single integer value. Each NewtonScript integer is 30 bits in
length. In packed font specifications, the lower 10 bits hold the font family, the
middle 10 bits hold the font size, and the upper 10 bits hold the font style.
These three parts added together specify a single font in one integer value. You can
use the constants listed in Table 8-6 at compile time to specify all of the needed infor-
mation. To do this, add one constant from each category together to yield a complete
font specification. At run time, of course, you’ll need to use the integer values.
