/** Objects containing all default panels.
*
* Panels are a mix of a component and a layout. They perform rendering operations, but also provide a draw area.
*
* By convention, all panels are of the form `def panel(id, area, params..., skin)(body): (Option[Value], PanelState[Rect])`.
* The returned value is the value returned by the body. Panels also return a rect, which is the area
* the panel must be called with in the next frame (e.g. for movable panels).
*
* As such, panels should be called like:
*
* ```
* val (value, nextRect) = panel(id, panelRect, ...) {area => ...}
* panelRect = nextRect
* ```
