From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>
Usually userspace don't want to have two overlay planes on the same zpos
so this change assign a different zpos for each plane. Before this change
a zpos of value zero was created for all planes so the userspace had to
set up the zpos of every plane it wanted to use.
