// Description : This maintains a list of images loaded up as "fade"
|
|
// images--that is, grayscale images whose only purpose
|
|
// is to adjust the source image to dark at the edges.
|
|
// It guarantees that each named image is only loaded
|
|
// once.
|
|
//
|
|
// Images are never freed from this pool. The
|
|
// assumption is that you have plenty of RAM for dealing
|
|
// with images.
