/**
 * Generate a PDF proof sheet on-the-fly of the current album or tag.
 * By Shad Laws.  Version 5, 2012/04/05
 * 
 * 2012/04/05, version 5
 *  Added ability to include GIF thumbnails if GD is installed (FPDF uses GD)
 *  Changed behavior of unhandled file types - now provides missing image icon instead of throwing an exception
 * 2012/03/30, version 4
 *  Major rewrite.  Output is similar, but everything "under the hood" is much cleaner and (I hope) more easily understood and tweakable by other users.
 *  Header link is now an icon.
 *  Fixed encoding problems with diacritic marks and special characters.
 *  Now includes FPDF as a library instead of requiring a separate installtion.
 * 2012/03/28, version 3
 *  Made sizing configuration more flexible
 *  Prettified code so it's easier to understand and tweak as desired
 *  Added header link
 *  First version properly documented and linked to Gallery wiki
 * 2012/03/27, version 2
 *  Determines jpg/png type by file header, not extension, which makes it robust against misnamed extensions
 *  (N.B.: there's a bug in some movie modules that copy missing_movie.png as a jpg thumbnail!)
 *  Made caption size limits to prevent overrun
 * 2012/03/27, version 1
 *  Initial release
