    Interface LineMetrics

    Measurements for one laid-out line, from Paragraph.getLineMetrics.

    All offsets index the paragraph's text in UTF-16 code units; all distances are in pixels.

    🧪 Not in the HTML Canvas standard.

        ascent: number;
        baseline: number;
        descent: number;
        endExcludingWhitespaces: number;
        endIncludingNewline: number;
