The FFGLPlugin API for adding parameters (FFGLPlugin::AddParam) does not provide the created param index.
And automatically uses the created param index as the param ID in the created ParamInfo.
So, if I want to use the inherited CFFGLPluginManager::SetParamGroup which expected a param ID, I can't, because I don't know the ID.
I can go through the params myself, find the param by name, and get it's index (thus it's ID).
So this is NOT a BLOCKER, but just an incomplete API.
