Using setImageOpacity() with Imagick Image driver adds a white background to the watermark image.
The line that causes this issue is:
https://github.com/fuel/core/blob/1.1/develop/classes/image/imagick.php#L77

Though this works fine with GD, but not Imagick or ImageMagick

Maybe we should allow a value of -1 (or someting else) for 'watermark_alpha' config value, so that the image opacity is not set.
