LiquidGlassBackdropGroup class

Shares backdrop input between non-overlapping fallback surfaces.

Wrap a screen or section containing several non-overlapping Liquid Glass widgets with LiquidGlassBackdropGroup to reduce Android blur passes to one.

Do not wrap multiple PageView pages or route transitions in one group: pages can overlap while moving, which can make grouped backdrop filters sample the wrong backdrop and visibly change color during the transition.
