pub struct DirectMeasureWithBaseline<F>(pub F, pub u64);Expand description
DirectMeasure whose closure also answers the first baseline:
(leaf, wrap_width) → (width, height, baseline).

Identity of this measurer (font scale, Dynamic Type state…). Two
consecutive passes with different ids invalidate every memo.
