// Description : A layer is a collection of non-overlapping
|
|
// DisplayRegions within a Channel that will be rendered
|
|
// together. When the channel renders, it will render
|
|
// all of its layers in index number order; each layer
|
|
// may overlap some or all of its DisplayRegions with
|
|
// other layers, and they will be drawn sequentially
|
|
// without clearing the framebuffer between layers.
