Would it be an alternative to only have one 
opencl filter that supports unsharp, deshake 
and all future features?

Or will all filters really be implemented very 
similar to the existing filters (with identical 
options) so that it makes perfectly sense to 
have them in one source file together with the 
existing filters and as the same filter for 
the users?
