Image modulus depth (minimum number of bits required to
support red/green/blue components without loss of accuracy).
The pixel modulus depth may be decreased by supplying a value
which is less than the current value, updating the pixels
(reducing accuracy) to the new depth. The pixel modulus depth
can not be increased over the current value using this method.
