Use the rounding macro which gives preference to rounding down in case two nearest values (high and low) are possible to raise the probability of cropping rectangle falling inside the bound region. This complies with the VIDIOC_G_SELECTION, VIDIOC_S_SELECTION ioctl description as documented in v4l uapi [1] which specifies that driver should choose crop rectangle as close as possible if no flags are passed by user-space, as quoted below : "``0`` - The driver can adjust the rectangle size freely and shall choose a crop/compose rectangle as close as possible to the requested one."
