function fillpdf_generate_pdf in FillPDF 5

Generates the PDF ouput based on field values It (1) constructs the XFDF from the form's fields, (2) saves the XFDF to /files/xfdf/x.xfdf, (3) redirects to the servlet at SERVLET_URL which downloads this XFDF, merges it with the user-specified PDF, and returns the output. The SERVLET_URL construct is SERVLET_URL?fid=10&nid=10 where fid is this form's id and nid is the node id from which data will be pulled via tokens.
