identify plugins that need layers

[0-wiz-0]

There's a port of gmic-qt for digikam here: https://github.com/cgilles/gmic-qt/
Using it I found out that some filters don't work. The plugin author wrote:

else some filters do not works in image editor as they requires layers from host application as Krita or Gimp. digiKam IE do not support layers. I don't find yet a way to disabled the filters requiring layers in GMIC-Qt.

Can you please tag filters that need layers, so they can be disabled in the digikam version of the plugin?
