Blend node
~~~~~~~~~~
The blend node blends two inputs using an optional opacity. It performs a blend operation
defined by the blend mode between both inputs, and mixes the result with the bottom input
using the opacity (defines by the *opacity* parameter, or the optional greyscale input).

Inputs
++++++
The blend node accepts three inputs:
* The first input is the top layer.
* The second input is the bottom layer.
* The third input is an optional mask that will be use instead of the opacity parameter.
Outputs
+++++++
The blend node outputs the result of the blend operation.
Parameters
++++++++++
The blend node has two parameters:
* The blend mode, that can be one of the following: Normal, Dissolve, Multiply, Screen,
Overlay, Hard Light, Soft Light, Burn, Dodge, Lighten, Darken, Difference.
* The opacity used when mixing the result of the blend operation with the bottom input
when the corresponding input is not connected.
Notes
+++++
The *opacity* input will be considered (and implicitly converted to) greyscale if it is a color texture.
