A zip file with a file pointing to /etc/passwd would, upon being cleaned by
mat2, produce a file with the filesystem's /etc/passwd file.

Thanks to Maxime Morin ( https://www.maijin.fr/ )
for the patch.

This should prevent the testsuite from breaking,
and marginally increase fingerprinting resistance.

Those issues were found via https://github.com/google/atheris

While hardcoding the compression to zipfile.ZIP_DEFLATED works for
most use cases of mat, being able to produce cleaned up uncompressed
zip files is useful for content that cannot be compressed more.

In addition it also enables to use mat2 for reproducible builds of
Android bootanimation files file that don't support compression.

It seems this was committed without intention to do so.

pyCairo by default renders the PDF surfaces with a resolution of 72
dpi which is so low that the bitmap gets blurred compared to original.

Since pyCairo 1.12.0, a new method set_device_scale(x_scale, y_scale)
is added, which allows changing the canvas resolution.

This should close #156

Because raising errors when unable to process
stuff instead of an exception is dumb.

This should close #151

Warn when there are encrypted fonts in an epub file

This should improve epub support

This is now required by ffmpeg
