There is none!! And there are not even comments in the source code. Just documenting the addXxxOpToFunctionData() would help immensely. I now understand the API a bit thanks to the use of it in some plugins, but there are still open questions anyway. What is addFetchOpToFunctionData() for? Does it fetch the color value from the window texture? tom
