// Class : DisplayRegion
|
|
// Description : A rectangular subregion within a window for rendering
|
|
// into. Typically, there is one DisplayRegion that
|
|
// covers the whole window, but you may also create
|
|
// smaller DisplayRegions for having different regions
|
|
// within the window that represent different scenes.
|
|
// You may also stack up DisplayRegions like panes of
|
|
// glass, usually for layering 2-d interfaces on top of
|
|
// a 3-d scene.
