Summary description: Convert PDF to PNG and compare PNG files after l3build

Announcement text:
----------------------------------------------------------------------


The l3build system is a useful and powerful tool for regression testing. With 
l3build you normally print the contents of some boxes from .lvt files to 
corresponding .tlg files. Sometimes LaTeX kernel or some package your package 
depends on adds a whatisit or \kern0pt, and your test files will fail even if 
the PDF files look the same as before and are still correct.

This ppmcheck tool provides an alternative way for regression testing: Instead 
of printing box contents in .lvt files, you could just convert PDF files to PNG 
files and compare PNG files after l3build finishes its job.
