OS X 10.11 text drawing

[slester]

We're drawing text in canvas to display math, and we're testing what node-canvas draws against what the browser draws for testing purposes. However, with the upgrade to El Capitan, this broke completely. The font size is ENORMOUS, easily 100x the size that is supposed to be drawn (and is drawn in canvas inside a browser). The exact same code has the desired result in 10.10.

Here are some screenshots of what happens:

Any ideas?

Yeah I've been seeing this as well :(

A workaround if to load the font from a .ttf file manually.

This is a problem with Cairo, the dependency of Canvas: https://bugs.freedesktop.org/show_bug.cgi?id=84324#c13

There're quite a lot of reports of this problem, affecting other packages, as well, e.g. JuliaGraphics/Cairo.jl#122
