;                 Serge Mankovski B/W Film Simulation
;
; 		Copyright Serge Mankovski (sevato@mankovski.com)
;                    Toronto, Ontario, 2007
;
;           Version 1.1  March 30,  2007
;           
; Converts selected layer into Black and White using channel mixer
; Uses channel presets found on Internet. I am not sure about the origin of these
; settings and I do not know if they really produce result resembling tonal qualities of
; the film, but it produces nice looking B/W and it is a useful way to convert to black and white
; 
; Change Log:
; Version 1.1
;		- added IR film simulation
;		- added color filters applied before b/w conversion
; 		- added saturation option
;		- Gimp 2.3.15+ support
;
; Version 1.1.1 Various fixes by Ari Pollak - thanks!
