I see that a kernel may contain "one or more" output members.
But neither the ShaderJob nor the filter usage in Flash allows for
more than one output. I have written a kernel that filters two
inputs (one a Vector.<Number> and one a BitmapData) to
corresponding outputs using a single criterion. This compiles OK.
Is there any way to use it from AS3? Otherwise I have to run two
shaders in sequence to accomplish this.
