Class Overview
A color filter that can be used to simulate simple lighting effects.
A LightingColorFilter is defined by two parameters, one
used to multiply the source color (called colorMultiply)
and one used to add to the source color (called colorAdd).
The alpha channel is left untouched by this color filter.
Given a source color RGB, the resulting R'G'B' color is computed thusly:
R' = R * colorMultiply.R + colorAdd.R
G' = G * colorMultiply.G + colorAdd.G
B' = B * colorMultiply.B + colorAdd.B
The result is pinned to the
[0..255] range for each channel.
