156b6a9490 Make wrapCharacters -> escapeString. Use a regex. 
The `htmlForScreenRows` benchmark went from ~3.5 ms to ~2.9ms for a 
call to htmlForScreenRows over the entire screen range.

5516dadffe Remove selective gutter rendering. 
It is faster but incorrect in the case of newlines. It will have to be 
rethought. It can be a different unit of work

d0be7fbf8e Add a character width cache based on scopes. 
This is slower than the position cache in the best case, but faster
in the worst and average case. With this, you can search for a space
in find and replace, and still scroll the buffer.

In editor.coffee, there are 10,500 spaces. To highlight all of them, 
the previous cache method took 7 seconds, this takes 2 when the cache 
is empty, and about 10ms when the entire file is cached.

8a3f137519 Speed up token html generation. 20ms -> 6ms 
Character replace was most of it. Removing regex creation, array 
creation and joins seems to reduce the GC pressure. Calling 500 times, 
GC spent 100ms less time.

a57c86f4ea Shortcut out of isHidden when we can. 
Checking computed style is an order of magnitude more expensive than 
checking the style property.

We know it's visible if it is on the dom and doesn't have
display == none set. This is an order of magnitude faster than the
default implementation which calls getComputedStyle()

914288ab86 Wrap each char in a span; compute left position by measuring each span. 
This is is faster and simpler than the old method. Running each function
20,000 times yielded these results:

Old: 3750ms
This method: 1523ms
By looking up each char's width in a dict: 29ms
