verticalBarBehavior property
Whether bars move into iPhone Duo's vertical bar strip.
Defaults to GlassVerticalBarBehavior.automatic: where the device reserves a strip, the pinned chrome stacks in it — back button first, then the leading and trailing groups in order — and the title stays in a horizontal row at the top of the content, beside any item that stays horizontal (see GlassBarActionItem.axisBehavior). GlassTabBar.bottom and GlassToolbar follow, from the bottom of the strip up. Read the result with GlassVerticalBar.maybeOf.
Only the shell's own subtree follows, and only while enabled: UIKit moves the bars a container owns and no others.
Implementation
