clipExpansion property
Extra clip budget forwarded to LiquidGlass.withOwnLayer on the Impeller
premium path. Use this to prevent the glass BackdropFilterLayer from
hard-clipping pixels that an ancestor Transform (e.g. jelly physics) has
pushed outside the tight geometry bounds.
Defaults to EdgeInsets.zero — no extra cost for static glass.
Implementation
final EdgeInsets clipExpansion;
