If true, egui consumed this event, i.e. wants exclusive use of this event (e.g. a mouse click on an egui window, or entering text into a text field).
For instance, if you use egui for a game, you should only
pass on the events to your game when
Self::consumed is `false.
Note that egui uses
tab to move focus between elements, so this will always be
true for tabs.
Do we need an egui refresh because of this event?
