<p>If <em>x_pos</em> is outside the line, <em>index</em> and <em>trailing</em> will point to the very first or very last position in the line. This determination is based on the resolved direction of the paragraph; for example, if the resolved direction is right-to-left, then an X position to the right of the line (after it) results in 0 being stored in <em>index</em> and <em>trailing</em>. An X position to the left of the line results in <em>index</em> pointing to the (logical) last grapheme in the line and <em>trailing</em> being set to the number of characters in that grapheme. The reverse is true for a left-to-right line.</p>
