windowed with overlap

[wimglenn]

Hello, thank you for this super useful and high-quality library!
I'm wondering if there is any support for windowed with overlap, e.g. by default there is overlap of the window size - 1

>>> g = windowed_iter(itertools.count(), 3)
>>> next(g)
(0, 1, 2)
>>> next(g)
(1, 2, 3)
>>> next(g)
(2, 3, 4)

But what if you want (0, 1, 2), (2, 3, 4), (4, 5, 7)... ? Any easy solution in boltons?
