Subject: [PATCH 4/8] Specify PDF minor version 1.7
Ghostscript 9.26 changed the default PDF output to 1.7 [1].
This causes a lot of warning messages in perfbook.log, saying:
pdfTeX warning: pdflatex (file ./cartoons/1kHz.pdf): PDF inclusion:
found PDF version <1.7>, but at most version <1.5> allowed
<cartoons/1kHz.pdf, id=11175, 319.79472pt x 287.27324pt>
File: cartoons/1kHz.pdf Graphic file (type pdf)
This warning can be suppressed by setting "\pdfminorversion=7"
in the preamble.
