Non-native fullscreen has certain limitations at the moment regarding
being truly fullscreen (taking all screen surface) and losing no
functionality when activated. Currently, tab functionality is lost when
non-native fullscreen is activated.
This commit introduces the `titled-visible-menu` mode for macOS
non-native fullscreen. Like `visible-menu` mode, it hides the dock and
uses its surface, leaving the menubar visible. This mode makes full use
of the screen (except for the menubar) while retaining the tabbar’s
functionality.
While a truly fullscreen non-native mode without feature loss is ideal,
this implementation provides a functional alternative in the meantime.
Finishes #378
Supercedes #4159
This adds a new enum value for `macos-non-native-fullscreen`:
`padded-notch`. This value will add padding to the top of the window to
account for the notch on applicable devices while still hiding the
menu.
This value is preferred over "visible-menu" by some people because for
screens without a notch, the window will take up the full height.
The plan in the future is that we may color the padded area when a notch
is present. In this commit it appears as transparent.
