/*
* NV_CTRL_GVO_X_SCREEN_PAN_[XY] - when GVO output of the X screen is
* enabled, the pan x/y attributes control which portion of the X
* screen is displayed by GVO. These attributes can be updated while
* GVO output is enabled, or before enabling GVO output. The pan
* values will be clamped so that GVO output is not panned beyond the
* end of the X screen.
