Internals (incomplete)
Note!
This section is still very incomplete and some facts are not true
anymore. This should be kept in mind. Currently I have no time to
write this section. But I try to keep figure
consistent to the current releases. This may lead to inconsistencies
between the text and the figure.
In this section, some information on internals of t1lib is given. There is
no need for an average user to read this section although having understood
what is going on internally might be helpful if problems occur.
The basic idea of this section is to describe the data structures and to give
information on when they are initialized, allocated and referenced. Figure
shows an image of the data-structures for the special case that
the font with ID 0 has already been loaded and several size-instances have
already been created.
Figure:
The internal data structures of t1lib. The
underlying substructures are shown only for the first font
FontID=0.

As the figure indicates, the complete area may be split into three
different sub-areas, thereby pointing out their logical functions.
