Currently, layers’ order depends on the module loading order.
With this patch, modules can safely add their own layer at the correct
place.

In orbital i have 10 layers, so these would not be enough. Besides,
having to modify libweston everytime i need one more would be a
hassle. I understand the problem, but i think it is a weston problem,
rather than libweston, and should be something on top, imho.
There is room between these values, specifically so you can add your
own. No need to modify Weston every time. These are just standard values
that plugins can use and developers are aware of, so you can make your
own values meaningful wrt these ones.
These values should be shared between the majority of compositors, so if
you have more to add that are meaningful outside of orbital, please share.
It cannot be a weston problem, IMO, because I really want
libweston-based compositors to share as much modules as possible, and
these modules could add their layers.
Cheers,
