Method GTK2.Pango.LayoutLine()->x_to_index()

Method x_to_index: mapping x_to_index(int x_pos)
Description: Converts from x offset to the byte index of the corresponding character within the text of the layout. If x_pos is outside the line, index and trailing 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 index and trailing. An X position to the left of the line results in index pointing to the (logical) last grapheme in the line and trailing set to the number of characters in that grapheme. The reverse is true for a left-to-right line.
