 //  1. Default (disabled)
 //  2. Enabled always (to allow dogfooding)
 //  3. Disabled always (to give safety fallback for users)
 //  4. Enabled only if we detect a highDPI display

 // Option #4 may soon be the default, because the feature is needed soon for
 // high DPI, but cannot be used (yet) for low DPI. Options #2 and #3 will
 // override Option #4.
