This should provide a better out-of-the-box experience when using PDF.js in a Node.js environment, since it's missing native support for both `@font-face` and `Image`. Please note that this change *only* affects the default values, hence it's still possible for an API consumer to override those values when calling `getDocument`. Also, prevents "ReferenceError: document is not defined" errors, when running the unit-tests in Node.js/Travis.
