Positioning hints for aligning a surface relative to a rectangle.
These hints determine how the surface should be positioned in the case that the surface would fall off-screen if placed in its ideal position.
For example, Gdk.AnchorHints.FLIP_X will replace Gdk.Gravity.NORTH_WEST with Gdk.Gravity.NORTH_EAST and vice versa if the surface extends beyond the left or right edges of the monitor.
If Gdk.AnchorHints.SLIDE_X is set, the surface can be shifted horizontally to fit on-screen. If Gdk.AnchorHints.RESIZE_X is set, the surface can be shrunken horizontally to fit.
In general, when multiple flags are set, flipping should take precedence over sliding, which should take precedence over resizing.
