backends: move windowing.py into backends--it is very backend-specific

backend_tkagg: one more typo from commit before last

backend_tkagg: fix major typo from last commit

backend_tkagg: show() gets an experimental kwarg for testing blocking mode.
By default, the behavior of show() is unchanged--it does not block, and
it forces interactive mode on. show(block=True) is intended to make
it behave the same as in the other common backends, blocking until
all figures have been closed.

windowing: add module docstring, fix import

Fix markerscale and scatterpoints keyword arguments in legend. Thanks to Erik Tollerud

Take stroke width into account when quantizing rectilinear paths. Discovered by Jason Grout in the mailing list thread "Plots shifted up or to the left a pixel or so"
