Guess zpos from plane type 
Many drivers don't expose the zpos plane property. We can guess it from the
plane type though: primary, overlay, cursor. Except some drivers expose
underlays too: underlays, primary, overlay, cursor. Underlay planes don't have a
special type, they are just marked as overlays. To detect them, check whether
their plane ID is less than the primary plane ID.

libhwc

Lightweight hardware composer library for libdrm.

libhwc eases the use of KMS planes from userspace without standing in your way. Users create "virtual planes" called layers, set KMS properties on them, and libhwc will allocate planes for these layers if possible.

Building

Depends on libdrm. Requires universal planes and atomic.
