PgGlyphItem.split

Modifies @orig to cover only the text after @split_index, and returns a new item that covers the text before @split_index that used to be in @orig.

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).

This function is similar in function to pango_item_split() (and uses it internally.)
