Returns the maximum intrinsic width of this modifier node.

fn min_intrinsic_height(&self, measurable: &dyn Measurable, width: f32) -> f32

Returns the minimum intrinsic height of this modifier node.

fn max_intrinsic_height(&self, measurable: &dyn Measurable, width: f32) -> f32

Returns the maximum intrinsic height of this modifier node.

fn create_measurement_proxy(&self) -> Option<Box<dyn MeasurementProxy>>

Creates a measurement proxy for this node that can perform measurement without holding a borrow to the modifier chain.
