class UIImage
# Operator shorthand for `apply_filter`, or coerces the image into other
# formats.
#
# @example
# image = 'test'.uiimage
# new_image = image | CIFilter.gaussian_blur # => returns a CIImage
# new_image = (image | CIFilter.gaussian_blur).uiimage # => coerce to UIImage
# new_image = image | CIFilter.gaussian_blur | UIImage # => coerce to UIImage via chaining
