To create a plug-in multipixel filter
You can define a plug-in DG node with at least two input attributes and one output attribute with a float type. The input attributes require the short name X and Y. The output attribute has to be connected to the Plug In Filter Weight attribute in the renderQuality node.
When the plug-in filter type is selected, the plug-in node is evaluated multiple times with different x and y weights, ranging in [-1..1]. The plug-in filter should be defined in the normalized domain [-1..1,-1..1]. The filter width change only affects the mapping of the normalized filter to the pixel coverage.
