    Bug 763996 - Where appropriate, change "gamma correction" to "gamma adjustment"
    
    Gamma correction refers to correcting how an image is displayed on
    various devices. Gamma adjustment is a more general phrase that also
    applies to adjusting gamma as a step in image enhancement in a
    color-managed workflow.
