set_anchor_hints
Description:
Set new anchor hints.
The set anchor_hints determines how surface will be moved if the anchor points cause it to move off-screen. For
example, `GDK_ANCHOR_FLIP_X` will replace `GDK_GRAVITY_NORTH_WEST` with `GDK_GRAVITY_NORTH_EAST` and vice versa if surface extends
beyond the left or right edges of the monitor.
