Title: Imbo needs a "level" transformation

To be able to change the level of RBG colors individually (and perhaps other parameters as well) Imbo needs to support some sort of level transformation. The [Imagick::levelImage](http://www.php.net/manual/en/imagick.levelimage.php) method can potentially be used for this.
