Overlong slides should be split up or reworked into a smaller slide

[michael-kerscher]

The original issue #1464 provides arguments on why scrolling on slides should be avoided.
To find slides that are interesting to rework I created #2234 and wrote a small tool to evaluate the slides.

I now did a first run of the new tool and these are the longest pages where the main content element is bigger than 1333 pixels (16:9 ratio if 750 pixels is the assumed width)

This is how I created the result. Filter the output for exercises, print summary, etc. only output MaxHeight violations, only output height in pixel, sort by height descending and create a link

$ python ./.github/workflows/run-evaluator.py book/comprehensive-rust-en/ violations-en.csv
$ grep -Po "(?<=html/).*MaxHeight" violations-en.csv | grep -v -e print.html -e exercises/ -e exercise.html -e solution.html -e glossary.html -e structure.html | sort -h -t, -k 2 -r | sed -e "s|^|https://google.github.io/comprehensive-rust/|" | cut -d, -f 1,3 | tr ',' ' '
