FPDF 1.86 - http://www.fpdf.org/
Author: Olivier PLATHEY

FPDF is released under a permissive license: there is no usage restriction.
You may embed it freely in your application (commercial or not), with or
without modifications.

Modifications made for CC Visual PDF Builder:
- the FPDF class is declared in the CCVPB\Libs namespace (no conflict with
  other copies of FPDF) and always uses the bundled "font" folder;
- font definition files return an array instead of defining variables;
- files are read and written with the WordPress filesystem API, PNG data is
  parsed in memory, dates use gmdate(), error messages are escaped.
