* #ClutterOffscreenEffectClass.create_texture() virtual function; no chain up
|
||||
* to the #ClutterOffscreenEffect implementation is required in this
|
||||
* case.
|
||||
*
|
||||
* ## Paint nodes
|
||||
*
|
||||
* #ClutterOffscreenEffect generates the following paint node tree:
|
||||
*
|
||||
* |[<!-- language="plain" -->
|
||||
* Effect
|
||||
* ├─────────┐
|
||||
* Layer Pipeline
|
||||
* │
|
||||
* Actor
|
||||
* ]|
|
||||
*
|
||||
* When the actor contents are cached, the generated paint node tree
|
||||
* looks like this:
|
||||
*
|
||||
* |[<!-- language="plain" -->
|
||||
* Effect
|
||||
* │
|
||||
* Pipeline
|
||||
* ]|
|
||||
*
|
||||
* In both cases, the "Pipeline" node is created with the return value
|
||||
* of #ClutterOffscreenEffectClass.create_pipeline().
