Work on line wrapping.

Rather than storing a needWrap flag, there is now a record of the last line
wrapped, so if a change requires some rewrapping then the wrapping is only
performed for the line of the change and subsequent lines.
If a change in styling spills off the end of a line, such as occurs by
starting a multiline comment, that style change may change the width of
subsequent text so rewrapping is performed.
When window resized, rewrap only done when width changed as resize may be
only vertical.
