This mixes in the Magick module, so that you don't need to preface its
module methods with Magick::

Compare the following:

$ irb
irb(main):001:0> sin(PI)
NameError: uninitialized constant PI
from (irb):1
irb(main):002:0> Math::sin(Math::PI)
=> 1.22464679914735e-16
irb(main):003:0> include Math
=> Object
irb(main):004:0> sin(PI)
=> 1.22464679914735e-16
