Detailed Description

OverlayElement representing a flat, single-material (or transparent) panel which can contain other elements.

Remarks
This class subclasses OverlayContainer because it can contain other elements. Like other containers, if hidden it's contents are also hidden, if moved it's contents also move etc. The panel itself is a 2D rectangle which is either completely transparent, or is rendered with a single material. The texture(s) on the panel can be tiled depending on your requirements.
This component is suitable for backgrounds and grouping other elements. Note that because it has a single repeating material it cannot have a discrete border (unless the texture has one and the texture is tiled only once). For a bordered panel, see it's subclass BorderPanelOverlayElement.
Note that the material can have all the usual effects applied to it like multiple texture layers, scrolling / animated textures etc. For multiple texture layers, you have to set the tiling level for each layer.
