PangoItem* pango_item_split ( PangoItem* orig, int split_index, int split_offset )
orig to cover only the text after
returns a new item that covers the text before
used to be in
You can think of
split_index as the length of the returned item.
split_index may not be 0, and it may not be greater than or equal
to the length of
orig (that is, there must be at least one byte
assigned to each item, you can’t create a zero-length item).
split_offset is the length of the first item in chars, and must be
provided because the text used to generate the item isn’t available,

Byte index of position to split item, relative to the start of the item.
Number of chars between start of
