Struct LineHeightStyle 

pub struct LineHeightStyle {
    pub alignment: LineHeightAlignment,
    pub trim: LineHeightTrim,
    pub mode: LineHeightMode,
}

How a line of text sits inside the height it was given.

A style that names one is laid out by AOSP’s StaticLayout rule — whole-pixel metrics, a font that a short line height cannot shrink, and the odd pixel of leading below the baseline. A style that names none keeps the framework’s plain arithmetic: the box is exactly the requested height with the leading split evenly. The two disagree by a device pixel on most faces, so a screen that draws through a crate::DrawScope and composes Text in the same frame has to state the same policy on both or the two sets of rows will not line up.
