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.

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.
