Detailed Description

       drag and drop actions

       This is a bitmask of the available/preferred actions in a drag-and-drop operation.

       In the compositor, the selected action is a result of matching the actions offered by the
       source and destination sides. 'action' events with a 'none' action will be sent to both
       source and destination if there is no match. All further checks will effectively happen on
       (source actions ∩ destination actions).

       In addition, compositors may also pick different actions in reaction to key modifiers
       being pressed. One common design that is used in major toolkits (and the behavior
       recommended for compositors) is:

       • If no modifiers are pressed, the first match (in bit order) will be used.

       • Pressing Shift selects 'move', if enabled in the mask.

       • Pressing Control selects 'copy', if enabled in the mask.

       Behavior beyond that is considered implementation-dependent. Compositors may for example
       bind other modifiers (like Alt/Meta) or drags initiated with other buttons than BTN_LEFT
       to specific actions (e.g. 'ask').
