Interface WindowOptions

where the stack puts it; 'bottom' is the usual place for a dialogue box

Whether a click anywhere is swallowed rather than reaching what is underneath, and closes the window when it lands outside it. A window left to itself is not clickable - only the widgets inside it are - so a click on a map under an open inventory still reaches the map; this is the layer that stops it, and the tap-outside-to-dismiss a phone user expects.

Off by default, since it is a change to what the whole screen answers to.

whether cancel closes it; false for a window that must be answered

Whether the world behind is dimmed. Defaults to true for a modal window.

A dialogue box over a conversation scene is the case for false: it takes the input like any modal, but the scene behind it is what the player is meant to be looking at, so dimming it would be backwards.

a modal window swallows input; anything below it stops responding
