advanced line-art script by lasm

["mbrethen" <mbrethen@xxxxxxxxx>]

This is from the script:

; Advanced Line Art  function:
;
; Requires:
;   plug-in-sobel
;   plug-in-gauss-rle
;   plug-in-gimpressionist
;   plug-in-grain
;   plug-in-convmatrix

Sobel and gimpressionionist I recognize; are the rest of these plugins=20
included in the standard gimp 2.2 installation? If=20
not, which ones? And where can I download them?

Thanks.
