PeachDrawing.Text.Outlines.GlyphOutline
GlyphOutline.IsGridFitted Property
Whether the outline was grid-fitted: its points were moved by the font’s own hinting so that the glyph lines up with the pixel grid at PixelsPerEm. It is false for an outline in design units, and for one asked for at a size that could not be hinted (the font has no hints of a kind that is supported, or its hinting program failed).
