I've made a new version of dvisvgm-hashes.lua. It compresses
consecutive page ranges, so it shouldn't crate such long page lists.
Moreover, if GNU Make is available on the system, it makes a Makefile,
which calls dvisvgm only on subset of pages (64 by default) and it
calls it in parallel (thanks to Reinhard for this idea). It should
speed up the compilation in theory, although I am not sure from my
tests that it really works in practise.

I can see it. I am not sure what is the issue, maybe Martin know? The
call to dvisvgm is in the form:

dvisvgm -v 4 -n --exact -c 1.15,1.15 -p 1-5 filename.idv 2> filename.dlog

You are missing the `pic-align` option I think.
