On Ubuntu 16.4 LTS, I just now installed rust nightly[1], and pathfinder[2], and the three demos appear to work in the default firefox 56, but not in chromium 61.0.3163.100[3]. Disk usage was half GB, split between ~/.cargo and pathfinder/ . Time was... less than a snack. My GPU was integrated Intel HD 520. I already had npm 3.10.3.

[1] https://www.rust-lang.org/en-US/install.html Select 2, for custom install, and change to "nightly". My host triple was x86_64-unknown-linux-gnu. [2] https://github.com/pcwalton/pathfinder [3] TextDemoView.initContext (view.ts:324) Uncaught (in promise) TypeError: Cannot read property 'createQueryEXT' of null .

EDIT: The three demos are: some text; the SVG tiger; some planar text in 3-space.
