/**
* VipsBlendMode:
* VIPS_BLEND_MODE_CLEAR: Where the second object is drawn, the first is removed.
* VIPS_BLEND_MODE_SOURCE: The second object is drawn as if nothing were below.
* VIPS_BLEND_MODE_OVER: The image shows what you would expect if you held two semi-transparent slides on top of each other.
* VIPS_BLEND_MODE_IN: The first object is removed completely, the second is only drawn where the first was.
* VIPS_BLEND_MODE_OUT: The second is drawn only where the first isn't.
* VIPS_BLEND_MODE_ATOP: This leaves the first object mostly intact, but mixes both objects in the overlapping area.
* VIPS_BLEND_MODE_DEST: Leaves the first object untouched, the second is discarded completely.
* VIPS_BLEND_MODE_DEST_OVER: Like OVER, but swaps the arguments.
* VIPS_BLEND_MODE_DEST_IN: Like IN, but swaps the arguments.
* VIPS_BLEND_MODE_DEST_OUT: Like OUT, but swaps the arguments.
* VIPS_BLEND_MODE_DEST_ATOP: Like ATOP, but swaps the arguments.
* VIPS_BLEND_MODE_XOR: Something like a difference operator.
* VIPS_BLEND_MODE_ADD: A bit like adding the two images.
* VIPS_BLEND_MODE_SATURATE: A bit like the darker of the two.
* VIPS_BLEND_MODE_MULTIPLY: At least as dark as the darker of the two inputs.
* VIPS_BLEND_MODE_SCREEN: At least as light as the lighter of the inputs.
* VIPS_BLEND_MODE_OVERLAY: Multiplies or screens colors, depending on the lightness.
* VIPS_BLEND_MODE_DARKEN: The darker of each component.
* VIPS_BLEND_MODE_LIGHTEN: The lighter of each component.
* VIPS_BLEND_MODE_COLOUR_DODGE: Brighten first by a factor second.
* VIPS_BLEND_MODE_COLOUR_BURN: Darken first by a factor of second.
* VIPS_BLEND_MODE_HARD_LIGHT: Multiply or screen, depending on lightness.
* VIPS_BLEND_MODE_SOFT_LIGHT: Darken or lighten, depending on lightness.
* VIPS_BLEND_MODE_DIFFERENCE: Difference of the two.
* VIPS_BLEND_MODE_EXCLUSION: Somewhat like DIFFERENCE, but lower-contrast.
