Reduce observation to single observeMarker method on display buffer
...
It will call the observer callbacks with the buffer and screen positions
of the head and tell each time any of these values is changed.

Rename to DisplayBuffer.observeMarkerHeadPosition
...
When you observe, you get callbacks whenever the screen or buffer
position changes, and you get the new and old position in both
coordinate types.

Build DisplayBufferMarker object to help track marker screen positions
...
There are 3 failures, which I think are attributable to the fact that
I'm not emitting events from the when the selection tail changes, and
I'm not emitting redundant events when the head is changed to the
same position it was previously, whereas before I wasn't guarding
against redundant events.

Pass old/new buffer and screen positions to marker position observers

This is needed by the snippets package, which needs to know where the

Tell marker head observers if a move was caused by a buffer change
...
This is used by cursor to only autoscroll when the marker head is
explicitly moved, so that passive movements caused by buffer insertions
don't trigger autoscrolling.

at all. The API user will access them by a returned scalar id rather
than calling methods on the returned anchor object directly.

Cache the maxScreenLineLength
...
Computing this requires a full scan of all screen lines. Here I keep it updated as I add / remove lines. If I remove the line with the max length, I am forced to scan all of them again. But this happens relatively rarely. Usually I only need to scan the lines I'm replacing and inserting.

Introduce LanguageMode wrapper for Ace modes as a foundation of our own modes
...
LanguageMode is the central point for all language-specific behavior associated with an EditSession. There is one LanguageMode instance per EditSession. LanguageMode has access to the EditSession and its TokenizedBuffer, and in reverse the EditSession, DisplayBuffer, and TokenizedBuffer also make use of LanguageMode. This is a bit incestuous, but I think it's okay because you can think of LanguageMode as a swappable strategy object that governs language-specific aspects of that constellation of objects.
