AnchorHints

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_ANCHOR_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_ANCHOR_SLIDE_X is set, the surface can be shifted horizontally to fit on-screen. If %GDK_ANCHOR_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.
