This patch adds a new Image Coordinates node for the compositor. The Texture Coordinates and Pixel Coordinates outputs were removed from the Image Info node and were added to the new node instead. Additionally, a new Normalized Coordinates output was added. The Pixel Coordinates output now no longer includes half pixel offsets.

* Static Cache Manager
|
|
*
|
|
* A static cache manager is a collection of cached resources that can be retrieved when needed and
|
|
* created if not already available. In particular, each cached resource type has its own instance
|
|
* of a container derived from the CachedResourceContainer type in the class. All instances of that
|
|
* cached resource type are stored and tracked in the container. See the CachedResource and
|
|
* CachedResourceContainer classes for more information.
|
|
*
|
|
* The manager deletes the cached resources that are no longer needed. A cached resource is said to
|
|
* be not needed when it was not used in the previous evaluation. This is done through the
|
|
* following mechanism:
|
|
*
|
|
* - Before every evaluation, do the following:
|
|
* 1. All resources whose CachedResource::needed flag is false are deleted.
|
|
* 2. The CachedResource::needed flag of all remaining resources is set to false.
|
|
* - During evaluation, when retrieving any cached resource, set its CachedResource::needed flag to
|
|
* true.
|
|
*
|
|
* In effect, any resource that was used in the previous evaluation but was not used in the current
|
|
* evaluation will be deleted before the next evaluation. This mechanism is implemented in the
|
|
* reset() method of the class, which should be called before every evaluation. The reset for the
|
|
* next evaluation can be skipped by calling the skip_next_reset() method, see its description for
|
|
* more information. */
