Tokens are associated with up to three classification numbers:

Class number: Broadest (least detailed) breakdown. For programs
that only care about gross token distinctions.
Major/minor numbers: Within their class, tokens have a major
number, and may also have a minor number to further
distinquish tokens with the same major number.

*** Class, major and minor token numbers are all >= 0 ***

Tokens that can't be classified are put in the "unknown" class.
For such, the major and minor numbers are meaningless, although
rtfTextBuf may be of interest then.

Text tokens are a single character, and the major number indicates
the character value (note: can be non-ascii, i.e., greater than 127).
There is no minor number.

Control symbols may have a parameter value, which will be found in
rtfParam.

RTFToken() return value is the class number, but it sets all the
global token vars.

rtfEOF is a fake token used by the reader; the writer never sees
it (except in the token reader hook, if it installs one).
*/

/*
Information pertaining to last token read by RTFToken. The
text is exactly as it occurs in the input file, e.g., "\{"
will be found in rtfTextBuf as "\{", even though it means "{".
These variables are also set when styles are reprocessed.
