[PyQt] Comparison of QPointF

[Vincent Vande Vyvre]

Hi,

I need to check the proximity of two QPointF for implement a snap grid 
behaviour, but the comparison of the two points is inexact or fail with 
Python3.

Platform    Linux-3.2.0-39-generic-x86_64-with-Ubuntu-12.04-precise
Python        2.7.3
Qt            4.8.1
PyQt        4.9.1
Sip            4.13.2

 >>> from PyQt4 import QtCore
 >>> QtCore.QPointF(172.0, 106.0) < QtCore.QPointF(5.0, 5.0)
True
 >>> QtCore.QPointF(5.0, 5.0) < QtCore.QPointF(172.0, 106.0)
False
 >>> QtCore.QPointF(-5.0, -5.0) < QtCore.QPointF(172.0, 106.0)
True
 >>> QtCore.QPointF(5.0, 5.0) < QtCore.QPointF(-172.0, -106.0)
False
 >>> QtCore.QPointF(172.0, 106.0) > QtCore.QPointF(5.0, 5.0)
False
 >>> QtCore.QPointF(172.0, 106.0) == QtCore.QPointF(172.0, 106.0)
True

TypeError: unorderable types: QPointF() < QPointF()
 >>> QtCore.QPointF(167.0, 101.0) == QtCore.QPointF(167.0, 101.0)
True
 >>> QtCore.QPointF(167.0, 101.0) <= QtCore.QPointF(167.0, 101.0)

Thanks
