; Pixel shader for doing the logic of the Game of Life
;  based on the accumulated neighbor and source texel
;  information accumulated in the green and blue color
;  channels on a previous pass.
;
; Set t0 to source field of averaged pixel values
;   which is the accumulation of neighbor & source pixel info
;
; Set t1 to "rules" texture which determines the resulting
;   pixel

; get colors from all 4 texture stages
tex t0                   ; source texture
texreg2gb t1, t0         ; looup into t1 based on t0 green and blue


; move result of dependent lookup into output
mov r0, t1
