Which are Texture Components and which ones Effects components?

GMM wrote in this thread here If you include an Image, Selection, Average Color, Minimum Level or Maximum Level component the filter will be correctly recognized as an Effect. However if the only Effect component is a Color control, such Effect filters will be rejected until the issue is fixed.

If I understand right what GMM have written, then it seems that all the Filter Forge components are divided and separated into two groups in the same way as the filters are separated, so there may be Texture Components and Effects components.

I did not know that this was this way, so now I wonder

Which are Texture Components and which ones Effects components?

As I can see the only ones I can guess are Color Controls and Image component as Effects components because they are related to input images that is not possible in the Texture filters.

Is important to know the difference between these components?

Or maybe they are only important for the submit wizard and submit server as it seems from the thread in the first link above

Oh, I see, then the only "Effects components" are only the ones included in the External category of the components bar and also the color control, all the other components are then considered "Texture Components"
