Whenever I look at dependency calculation, it takes me a while to get my
head round the concept of influences. If what I've written here is
accurate, maybe the next person to look at this (or my future self)
will need less of a run-up.

Tightened the escaping per this review comment:

(I didn't introduce a $tmp, as $val was local to that block already, and each
hex encoding is in its own C string literal to avoid consuming subsequent
chars that are valid hex digits.)

install prerequisite Perl modules in the systemwide locations. They may
have to be installed under the home directory, such as by using local::lib
(which is how the cPanel Perl-module installer works, on systems that use it).
For that to work, the local::lib-defined value for PERL5LIB must be in
the environment when Perl starts up. The former way %config{ENV} was handled
was too late, depending on the Perl code to unpack it from the storable and
put it into the environment.
Easy solution is to build the wrapper to repopulate the environment based on
%config{ENV} before ever exec'ing Perl (and then remove it from the storable
as there is nothing more that the Perl code will need to do with it).

This avoids potential action-at-a-distance from locally redefining $/
but never reaching the end of the redefinition's scope.

in analogy to sparklines, this renders scaled imgs to
data:img/...;base64,... urls in preview mode.
if the image is already present on the server (eg because it was not
just inserted), the already rendered image is referenced instead.

there is now a size calculating part (which chooses a final size) and a
scaling part (which triggers if the sizes calculated by the former
indicate a downscaling).
this solves the issue of unproportional upscalings
(bugs/image_rescaling_distorts_with_small_pictures).
also, "small" pdf files (or pdf files without explicit size settings),
which would not be converted under the old mechanism, now get rendered
to pngs.
this commit affects a unit test: while svgs were previously
unconditionally rendered to pngs, this now only happens on downscaling.
this is intentional -- while a small version of an svg graphic is
likely to be more compact when rendered (eg as a preview), a large
version would not have that benefit, and why convert something that
browsers basically can show and be inconsistend with how other images
are handled. the new unit test simply makes the original svg larger to
check for the same behaviros as before.

just install -extra to make it work

this allows picking a page from a pdf. also, this enhances performance
greatly when rendering pdfs, as only the first page is rasterized.
(otherwise, imagemagick would treat the pdf as a list of images, work
with all of them, until finally only the first page gets saved). the
default parameter of 0 will select the single image contained in typical
image files anyway, so no specialcasing between single- and multifile
containers is needed.

this is trivial as pdf is supported by imagemagick, and just needs an
explicit mention to enable conversion.

imagemagick, when reading an image, sets its magick parameter to
indicate the file type, overriding the explicitly set file type for
output if it is set at creation.
as a result, previously (with graphicsmagick-libmagick-dev-compat
1.3.18-1 providing Image::Magick), svg output files were not png,
neither svg, but mvg (imagemagick vector graphics).
