set_no_clear_hint
Description:
Sets whether the this should clear itself at the beginning of each paint cycle or not.
Clearing the Stage can be a costly operation, especially if the stage is always covered - for instance, in a full-screen video player or in a game with a background texture.
This setting is a hint; Clutter might discard this hint depending on its internal state.
If parts of the stage are visible and you disable clearing you might end up with visual artifacts while painting the contents of the stage.
