# Explanation of the filters:
#
# If, for example, red is set to "a b c d",
# where a, b, c, and d are four numbers,
# then the output red value for a given input
# color will be computed as follows:
#
# output_red = ( a * input_red +
# b * input_green +
# c * input_blue ) / 256 + d
#
# So, a, b, and c are scale factors
# (out of 256) for how much weight the input
# red, green, and blue components have in the
# output color, and d is a constant base
# value for the output.
#
# Below are some sample filters, which should
# make everything more clear.
#
