TryMeasureCharacterBounds possibly incorrect

[gerdus]

The character bounds returned by TryMeasureCharacterBounds looks wrong to me as the character does not fit into the box.

If I use a CustomGlyphBuilder like in one of the samples it is correct:

If you agree this is a bug I will attempt a pull request.

Code:

        public static void BoundingBoxes()
        {
            FontCollection collection = new();
            collection.AddSystemFonts();

            var family = collection.Get("Segoe UI");
            var emojiFamily = collection.Get("Segoe UI Emoji");
            var runText = "Hello WorLLd goodbye";

            var runRTO = new RichTextOptions(family.CreateFont(72, FontStyle.Regular))
            {
                Origin = new PointF(10, 20),
                WrappingLength = -1,
                FallbackFontFamilies = new[] { emojiFamily },
                WordBreaking = WordBreaking.BreakWord
            };

            using (Image<Rgba32> image = new Image<Rgba32>(800, 150))
            {
                image.Mutate(x => x.Fill(Color.White));
                TextMeasurer.TryMeasureCharacterBounds(runText, runRTO, out var bounds);

                foreach (var cbound in bounds)
                {
                    var dRect = new RectangleF(cbound.Bounds.X, cbound.Bounds.Y, cbound.Bounds.Width, cbound.Bounds.Height);
                    image.Mutate(x => x.Fill(Color.Gainsboro, dRect));
                    image.Mutate(x => x.Draw(Pens.Solid(Color.Teal, 1), dRect));
                }

                image.Mutate(x => x.DrawText(runRTO, runText, Color.Black));
                image.Save(@"T:\BoundingBoxes.png");
            }

        }

Definitely looks like a bug. A PR would be most welcome. Thanks!
