pdf_get_value for font metrics keys, with font descriptor modifier does not handle the descriptor correctly:

example code :

$pdf = pdf_new();
pdf_open_file($pdf, "");
pdf_begin_page($pdf, 595, 842);
$font = pdf_findfont($pdf, "Times-Roman", "winansi",0); 
pdf_get_value($pdf,'ascender',$font);
pdf_end_page($pdf);
pdf_close($pdf);

output:
Fatal error: PDFlib error: Bad font descriptor 1 in PDF_get_value/descender 

fix: 
pdf_get_value($pdf,'descender',$font-1);

When several fonts are (pre-)loaded, only query to the last one fails. The returned value for the others are probably mixed up.

This is allready fixed in the current CVS Version. Also the next minor Release of PDFlib (V4.0.2) will contain the bugfix in the companion wrapper code.
