501e1f2f7e [symfont] Remove another level of indirection 
Saves another few percents, though not as much as previous commit.

7fd9dce0e9 [symfont] Speed up a bit 
Remove one level of indirection in access to point data in generated
functions; ie. use p0, p1, ... instead of P[0], P[1], ...

Makes for about 10% speedup.

5c723ebfb0 [feaLib] Don't assume feature has lookups in DFLT 
It's possible for all of a feature's lookups to be in specific script
and/or language systems, so this code could crash.

e2186dec53 [feaLib] Don't set language when script is unset 
Before, if someone tried to set the language before setting the script
a None/language language system would be created (with actual tag
"None" stored in the feature table). This defaults to tag DFLT and
fails when a non-dflt language is set for DFLT, since that's illegal.

d1af1cfd4a [feaLib] Fix exclude_dflt handling 
This is to fix what I think was a misunderstanding of the exclude_dflt
keyword (and the implicit include_dflt option active by default).

Rather than including the following lookups in the default language
systems, I think it is used to include the lookups specific to default
language systems in the system defined by the current language
statement. Thus instead of registering a lookup in all default
systems when include_dflt is true, we should exclude the lookups
registered with default systems from the current system when
include_dflt is false.

71fb49962a Improve perimeterPen tests 
The tolerance on the pen is set to 0.5%, so it does not make sense
to test for accuracy for anything more than integers given the
values.

c34739760c [symfont] Handle closePath() 
Apparently some draw() implementations expect closePath() to
draw a line to the contour beginning.

In fact, looks like fontTools's TrueType draw() always does the
lineTo() before closePath(), but the CFF draw() doesn't.

7822958fa5 [symfont] Negate sign in green() function 
Following the theorem declaration:
https://en.wikipedia.org/wiki/Green%27s_theorem

we should negate the result.  Ie, for a counter-clockwise curve,
the area must be positive.
