ENH: make quickshift more tolerant to input type, just convert to float. Also keep track of random seed for reproducable tests.
...
Finally, do a unique on the output and add testing.

BUG: Fix OTSU thresholding tests with matplotlib IO plugin.

The matplotlib IO returns float arrays from [0, 1], which gives difference
results than a ubyte array. Explicitly convert to a ubyte array in the tests.

their filenames. This is now the behaviour of ImageCollection.

BUG: Ignore colorconv RuntimeWarning:invalid value encountered in true_divide.
...
Sometimes zero divided by zero can occur in this code. Saturation was already
explicitly set to zero when 'delta' is zero. According to Wikipedia, hue is
undefined when 'delta' here is zero, so explicitly set to zero.
