org.apache.isis.viewer.dnd.view.text.CursorPosition
Represents the position of a line cursor within a TextContent. The character position for a line extends from zero to text.length + 1. Where 0 means the cursor is to the left of the first character, and 1 is to right of the first character and to the left of the second character.

    @Override
    protected void drawHighlight(final Canvas canvas, final int maxWidth) {
        final int baseline = getBaseline();
        int top = baseline - style.getAscent();


        final CursorPosition from = selection.from();
        final CursorPosition to = selection.to();


        final String[] lines = textContent.getDisplayLines();
        final int displayFromLine = textContent.getDisplayFromLine();
        final int displayToLine = displayFromLine + lines.length;
        for (int i = displayFromLine; i <= displayToLine; i++) {
            if ((i >= from.getLine()) && (i <= to.getLine())) {
                final String line = textContent.getText(i);
                int start = 0;
                int end = style.stringWidth(line);


                if (from.getLine() == i) {
                    final int at = Math.min(from.getCharacter(), line.length());
                    start = style.stringWidth(line.substring(0, at));
