public GlyphItem split (string text, int split_index)
Modifies this 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 this.
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 this (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 split (and uses it internally.)
