PeachDrawing.Text.Layout.PlacedRun
PlacedRun.IsGenerated Property
Whether the run is not text of the paragraph but drawn in it: the hyphen a line broken inside a word ends with, or the ellipsis of a line that is cut. Its Range is empty, and a caret at the place it is generated is before it (after it, for a right-to-left paragraph). It is drawn like any other run.
