Changing ROI Parameters "On-the-Fly"

Making ROI parameter changes "on-the-fly" means making the parameter changes while the
camera is capturing images continuously. On-the-fly changes are only allowed for the parameters
that determine the position of the ROI, i.e., the Offset X and Offset Y parameters. Changes to the
ROI size are not allowed on-the-fly.
