Prevent arbitrary file read via zip archives
...
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.

zip archives: keep individual files compression type
...
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.

Fix pdf issues on printers

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.
