Giovanni Campagna 859ea1457d Add the ability to add shader hooks to MetaBackgroundActor
Using ClutterEffect is not pratical on MetaBackgroundActor, as the FBO
redirection has a noticeable performance impact. Instead, allow adding
GLSL code directly to the pipeline used to draw the background texture.
At the same time, port MetaBackgroundActor to modern Cogl API.
