/* the exact result of the grain-extract and grain-merge modes
* depends on the choice of (gamma-corrected) midpoint intensity
* value. for the non-legacy modes, the midpoint value is 0.5,
* which isn't representable exactly using integer precision. for
* the legacy modes, the midpoint value is 128/255 (i.e., 0x80),
* which is representable exactly using (gamma-corrected) integer
* precision. we therefore use the legacy modes when the input
* image precision is integer, and only use the (preferable)
* non-legacy modes when the input image precision is floating
* point.
*
* this avoids imperfect reconstruction of the image when using
* integer precision. see bug #786844.
