Comment 7 for bug 937202

This effect works on a .png and .svg file.
It applies a transparency (when you are using a low value, e.g. 0.10 or 0.20) at a logo. This one is transparent on all the length of the file. It is not possible with the others features which provide a transparency only on the first part of the image clip but at the end he becomes like it is at his initial state.
And with this one, we will have 14 news effects (I am not superstitious but I don't like the number 13). :-(
I had none problem with this one on my tests and nothing in the console like feedback.
