Channel modulus depth. The channel modulus depth represents
the minimum number of bits required to support the channel without loss.
Setting the channel's modulus depth modifies the channel (i.e. discards
resolution) if the requested modulus depth is less than the current
modulus depth, otherwise the channel is not altered. There is no
attribute associated with the modulus depth so the current modulus
depth is obtained by inspecting the pixels. As a result, the depth
returned may be less than the most recently set channel depth.
Subsequent image processing may result in increasing the channel depth.
