Vivianne Langdon 31012d5b8f Yet another reorganization, and solve Christine's 'rude problem' ... - We change the stream iterator to *always* return a grapheme (except for EOF). The grapheme then gets built up over time. - This way, trans flag for example is first white flag, then white flag + zwj, etc until it finally transforms into the trans flag. - Users of the stream library can then use the `modification?' flag to determine if the stream value is a modification of the prior grapheme instead of a new grapheme. - Abstracted iteration to an iterator object to support use cases where we don't have an input stream (reflow needs this!)		2024-03-05 11:46:32 -05:00
