Rendering Class

Since we want the final PDF document which potentially includes many chapters in it to look more as a book and have a nice Table of Contents, we need to change the default structure of "=head1" specs, so the "=head1 NAME" becomes a title of the chapter and removed from the POD source, therefore we need to bump up all the remaining "=headX" headers by one. i.e. "=head1" is rendered as "=head2", "=head3" as "=head3", etc. Therefore we override the super class's methods "view_head{1-4}". In addition we put <a name> anchors next to the headers so the PDF document can be hyperlinked if the reader supports this feature.

view_seq_file() is overriden too. Here we search for the file relative to the location of the document and if we find it we include its contents since the PDFs are created for making dead tree copies and therefore linking is not an option. Notice that it's OK to say F</etc/passwd> since it won't be found unless you actually put it under the current documents path or put the source document in the / path.

view_verbatim() is overriden: renders the <pre>...</pre> html, but defines a CSS class "pre-section" so the look-n-feel can be adjusted. in addition it splits text into 40 lines chunks. This solves two problems:

• "html2ps" tries to fit the whole <pre>...</pre> in a single page ending up using a very small unreadable font when the text is long.
• "ps2pdf" fails to convert ps to pdf if the former includes <pre>...</pre>, longer than 40 lines in one chunk.

The following rendering methods: anchor() and view_seq_link_transform_path() are defined in the "DocSet::Doc::Common" class and documented there.
