This patch adds a new Relative To Pixel node in the compositor. The node
converts values that are relative to the image size to values that are
in terms of pixels.
This is useful to use relative values in nodes that take pixel values.
For instance, the Kuwahara node has an input that defines the filter
size in pixels. If one wants to define it relative to the image size
instead, one can use this node.
The node can operate on float and 2D vector values. Further, the node
can do the conversion relative to a number of image properties:
- Per Dimension: Each dimension gets converted independently. The X
value is relative to the X dimension and the Y value is relative to
the Y dimension. This mode is special because in float mode, the
output will be a factor as opposed to a float.
- X: Relative to the x dimension.
- Y: Relative to the y dimension.
- Greater: Relative to the greater dimension.
- Smaller: Relative to the smaller dimension.
- Diagonal: Relative to the diagonal of the image.
