<P>
A token marker that splits lines of text into tokens. Each token carries
a length field and an indentification tag that can be mapped to a color
for painting that token.<p>
For performance reasons, the linked list of tokens is reused after each
line is tokenized. Therefore, the return value of <code>markTokens</code>
should only be used for immediate painting. Notably, it cannot be
cached.
