 			The default tooltip text. The tooltip appears when the user's mouse cursor stays idle over this control for a few moments, provided that the [member mouse_filter] property is not [constant MOUSE_FILTER_IGNORE]. The time required for the tooltip to appear can be changed with the [member ProjectSettings.gui/timers/tooltip_delay_sec] option. See also [method get_tooltip].
 			The tooltip popup will use either a default implementation, or a custom one that you can provide by overriding [method _make_custom_tooltip]. The default tooltip includes a [PopupPanel] and [Label] whose theme properties can be customized using [Theme] methods with the [code]"TooltipPanel"[/code] and [code]"TooltipLabel"[/code] respectively.
