vf_dnn_processing.c is designed to cover all the cases for image/video
processing with M inputs and N outputs (currently only M=1 and N=1 is
supported), covering the features of vf_sr.c and vf_derain.c. To avoid
duplicate/similar code in different filters, we don't add more feature in 
vf_sr.c/vf_derain.c, we just keep supporting their current feature.
