Noah Petherbridge f9b305679a Tooltip Widget and Event Refactor ... * Tooltip can be added to any target widget (e.g. Button) and pop up on mouse over. * Refactor the event system. Instead of passing a render.Point to all event handlers, pass an EventData struct which can hold the Point or the render.Engine. * Add event types Computed and Present, so a widget can set a handler on whenever its Computed or Present method is called.		2020-03-09 17:13:33 -07:00
