Stephen Bloch 39629e8e99 map-image and map-image/extra now give their function argument x and y ... coordinates, or not, depending on the arity of that function. This enables one to write a simple function from color -> color and immediately map it on an image. For the situation in which the function is location-dependent, one can still write a function from x,y,color -> color and map this on the image.		2011-12-02 07:09:37 -05:00
