Cargo Features

[dependencies]
servo-glutin = { version = "0.15.0", default-features = false, features = ["headless", "image"] }
default = image

The image feature is set by default whenever servo-glutin is added without default-features = false somewhere in the dependency tree.

headless

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
