Bug#818363: Uses unreproducible internal font IDs

[Damyan Ivanov]

Package: libpdf-api2-perl
Version: 2.025-1
Severity: wishlist
Tags: patch upstream

The TrueType, BdFont, CoreFont and Postscript subclasses of 
PDF::API2::Resource::Font append '~'.time() to the resource identifiers they 
generate. This is unnecessary because the identifier already includes the 
result of the pdfkey() function, which gives increasing numbers through a 
process lifetime.

Adding time() is in itself not enough to guarantee unique IDs, but only 
introduces unreproducible output and poses a slight performance penalty for the 
syscall needed to get the current time.

The attached patch removes time() from the resource IDs, which is sufficient to 
get reproducible output.
