savefig: make the "transparent" kwarg work as advertised

Add interpolation option to fill between so intersections are not broken. Thanks to Joonas Paalasmaa (Bug #2978358) for the report and initial implementation.

Fix path simplification -- distance threshold should have been squared.

contourf_demo: illustrate use of set_under and set_over with contourf colors kw

contouring: fix various bugs

Expose tolerance argument to image_comparison decorator. Use it to raise the tolerance for the test_figimage test.

dates: DateLocator.nonsingular checks for near-singularity.
Also fixed fill_units test and baseline files

axes: fix autoscale_view for test_axes/single_date test, and update
test output.

In the old version, single_date was behaving as if tight autoscaling
were in effect; now it puts the viewLim on tick marks.

axes: set _tight default to False; restore previous nonsingular expander

Remove unused import.
