8712c20156 [perimeterPen] Use Gauss-Legendre instead of Lobatto-Gauss for qudratic 
Uses one fewer point and is no uglier.

Is twice faster than the exact algorithm.

[perimeterPen] move source encoding declaration to the first line 
Otherwise I get this error on python2.7:

SyntaxError: Non-ASCII character '\xc2' in file perimeterPen.py on line 87, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

3e74798499 [perimeterPen] Add Gauss-Lobatto quadrature approximation implementation 
Is about 30 percent faster than recursive approach for the default .005
error tolerance.  To be optimized more.

[t2CharStringPen] use abs() instead of math.fabs() 
abs ends up calling fabs for floats anyway, and is a bit faster if 'number' is an int

[t2CharStringPen] always round the advance widths regardless of roundTolerance 
hmtx only can have integer values, so it would be weird to have widths as float in CFF...

[t2CharStringPen] disable rounding coordinates; add 'roundTolerance' argument 
Rounding of coordinates is now disabled by default.

The pen now accepts an optional 'roundTolerance' float, with values between
0 and 1 (default is 0).

Values >= 0.5 mean round all coordinates to integers.

Values between 0 and 0.5 mean round only when the absolute difference
between the original float and the rounded integer is within the tolerance

Fixes #769

consistently do sys.exit(unittest.main()) in all test modules 
So that when run as scrips they report test failures with exit code

code.

870b7ce92a Allow single-point open contours in area pen 
Sometimes an anchor is drawn as a moveTo followed by an endPath, for
that case it makes sense just to ignore and count the area as zero.

f3ff2f8881 pointInsidePen: add getWinding() 
Resolves https://github.com/behdad/fonttools/issues/621#issuecomment-234764830

Although, leaving contours left open is out of protocol behavior
IMO.

b0b049774c Implement analytical curve length for quadratic beziers 
This is multiple times faster, and tolerance-independent.

I'll explain how I arrived at this later.

56c27f45c9 Speed up perimeterPen 
It's still too slow, but an improvement.

Also, remove duplicate copy from symfont.

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.
