        //   (a) The unselected region before the selection.
        //   (b) The selected region.
        //   (c) The unselected region after the selection.
        // First, map the selected region offsets to be relative
        // to the start of the region and then map them to view
        // offsets so that they take into account characters not
        // present in the model.
        int mappedSel0 = mapOffset(Math.max(sel0 - p0, 0));
        int mappedSel1 = mapOffset(Math.min(sel1 - p0, p1 - p0));

        if (mappedSel0 > 0) {
            // Draw an initial unselected region
            x = drawUnselectedText(g, x, y, 0, mappedSel0);
