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

3d4bd76a76 [perimeterPen] Add Gauss-Lobatto implementation for quadratic Bezier as well 
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.

25083502e4 [perimeterPen] Update check for cusps 
If p1 coincides with p0 or p2, we still can use the lineTo()
code.

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.
