   # Blend mode to use when compositing images. See {Image#composite}.
   #
-  # `:clear` - where the second object is drawn, the first is removed
-  # `:source` - the second object is drawn as if nothing were below
-  # `:over` - the image shows what you would expect if you held two semi-transparent slides on top of each other
-  # `:in` - the first object is removed completely, the second is only drawn where the first was
-  # `:out` - the second is drawn only where the first isn't
-  # `:atop` - this leaves the first object mostly intact, but mixes both objects in the overlapping area
-  # `:dest` - leaves the first object untouched, the second is discarded completely
-  # `:dest_over` - like `:over`, but swaps the arguments
-  # `:dest_in` - like `:in`, but swaps the arguments
-  # `:dest_out` - like `:out`, but swaps the arguments
-  # `:dest_atop` - like `:atop`, but swaps the arguments
-  # `:xor` - something like a difference operator
-  # `:add` - a bit like adding the two images
-  # `:saturate` - a bit like the darker of the two
-  # `:multiply` - at least as dark as the darker of the two inputs
-  # `:screen` - at least as light as the lighter of the inputs
-  # `:overlay` - multiplies or screens colors, depending on the lightness
-  # `:darken` - the darker of each component
-  # `:lighten` - the lighter of each component
-  # `:colour_dodge` - brighten first by a factor second
-  # `:colour_burn` - darken first by a factor of second
-  # `:hard_light` - multiply or screen, depending on lightness
-  # `:soft_light` - darken or lighten, depending on lightness
-  # `:difference` - difference of the two
-  # `:exclusion` - somewhat like `:difference`, but lower-contrast
