ef8db1eebf Premultiply alpha channel to avoid dark artifacts during tranformation 
Add `Sharp.compare(file1, file2, callback)` function for comparing images
using mean squared error (MSE). This is useful for unit tests.

See:

dce36e0074 Add normalize() for simple histogram stretching 
Available as normalize() or normalise().
Normalization takes place in LAB place and thus should not change any
colors.

Existing alpha channels are preserved untouched by normalization.
