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:

64f7f1d662 Add experimental overlayWith API 
Composites an overlay image with alpha channel into the input image (which
must have alpha channel) using ‘over’ alpha compositing blend mode. This API
requires both images to have the same dimensions.

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.

125ee836fe Let libvips check whether we received a valid image or not 
This removes the custom image fingerprinting code and uses the libvips
is_a_buffer() infrastructure instead.
