dim(x,y) Dims x by y, x is the dimming get, y is the dimming amount. It is a vector function

dim(x,y)=clampmin(x-y,0)

dim(perlincubic(x*a/w,y*a/h,10,.5),cellnoise(x*a/w,y*a/h,1))+3*i

perlincubic(x*a/w,y*a/h,10,.5)-cellnoise(x*a/w,y*a/h,1)+3*i

var v=vec2(rx,ry)*a/w; var v1=round(v); step(e,length(dim(v,v1)))
