Hi Gustavo, I had already a review but I didn't give any comment to you. Sorry about that. This patch looks good to me but one thing isn't clear. Below is my comment.

I think cursor should by default be the top layer (if the hw can do it). Otherwise it will be really confusing to compositors I fear. -Daniel
