//! Inspired by WebKit's quirks.cpp[1], this file centralizes all our
//! sad environment-specific hacks that we have to do to make things work.
//! This is a last resort; if we can find a general solution to a problem,
//! we of course prefer that, but sometimes other software, fonts, etc. are
//! just broken or weird and we have to work around it.
