Directional Blur node
The Directional Blur node applies a Gaussian blur algorithm to its input in a given direction.

Inputs
The Directional Blur node accepts an RGBA input to be blurred and an optional blur mask that defines the intensity of the blur effect.
Outputs
The Directional Blur node outputs the result of the blur operation.
Parameters
The Directional Blur node has four parameters:
The grid size defines the size of the output image.
The mode spcifies whether the blur will move in one direction or both.
The sigma parameter defines how smooth the output will be.
The angle specifies the angle of the blur algorithm.
Notes
This node outputs an image that has a fixed size.
