The off pun is rather awful, but it does have precedent, and is
more succinct.

Issue #755

Closes #782

Correct highlighting for the following code snippet should highlight the + as an operator, and each 2 as a number (taken from http://clojuredocs.org/clojure_core/1.2.0/clojure.test/deftest)

    (is (= 4 (+ 2 2)))

 - Background parsing now never goes past the visible part of the
   document.

 - We only store style information for lines that are actually visible
   (and then keep it cached).

 - When the document changes, background highlighting always
   re-highlights from the change to the end of the visible part.

 - Gets rid of compareState mode methods and the hairy heuristic that
   tried to simulate it when absent.

 - The onHighlightComplete callback was removed, since it no longer
   really applies -- the document is only fully parsed when scrolled
   to its end.

This should help preserve memory (a huge document will no longer
immediately have parser state and highlighting information built up
for all lines, but only for the parts that you look at), and removes
the pathological case when you, for example, are typing at the top of
a huge XML document, and opening or closing a tag causes a whole
re-highlight to cascade all the way to the bottom because the
compareState will detect a change.

Issue #688

Fixes a problem where the editor would always be 30 pixels smaller
than its set height.

The height is now set on the outer wrapper DIV again, and some
height: 100% tricks are used to make height information flow
both ways (inside-out in demo/resize.html mode, outside-in in
normal, fixed-height mode).

The hack is horrible, but it seems to do the trick.

Also simplifies context-menu handling somewhat.

Issue #755

Some things appear to trigger it to scroll, with very bad
effects.

(And codemirror.css from a relative link.)

Closes #756

Closes #759

Closes #761

Closes #764

Fix bad rules in themes, measure width correctly.

Closes #765

It was passing undefined to setTimeout.

Closes #763

Closes #760 and fixes line backgrounds ending up behind editor background.

Discussion in issue #762

By clipping its top/bot to the borders of the outer div

The previous one broke line numbers

A *real* cleanup / reorder is becoming painfully needed, but this'll at
least make the tests pass.

Add CodeMirror.defineOption function for defining new options.

Add findMatchingBracket to the methods exported by this extension.

Closes #746

Prevents styled backgrounds from hiding the selection

It is now more structured (knows about ranges) and allows automatic
unfolding when the cursor enters the folded range.
