There are some Core Image Filters that are not supported in this version. Some of them, such as the convolution group, will likely be added with some simple changes. There are a couple of undocumented filters that do not have a clear use or interface. And finally several are meant to only be internal to the operation of other filters. I may add custom filters that incorporate this group.
