|
// Description : This is a special TextNode that automatically updates
|
|
// itself with the current frame rate. It can be placed
|
|
// anywhere in the world where you'd like to see the
|
|
// frame rate.
|
|
//
|
|
// It also has a special mode in which it may be
|
|
// attached directly to a channel or window. If this is
|
|
// done, it creates a DisplayRegion for itself and renders
|
|
// itself in the upper-right-hand corner.
