The plugin mechanism is built into the effects class itself, not the
application. The application gets all the data it needs (such as plugin effect
name, etc...) by calling the effect class. All the application really needs to
know is the label of the plugin and how to call it. Since you give the methods
the canvas or pixmap when applying an effect, the plugin can get the rest of
the data it needs from that.

This allows us to use the same plugins easily in different apps.
