Documentation

Alpha is setup with drm_plane_create_alpha_property(). It controls the
plane-wide opacity, from transparent (0) to opaque (0xffff). It can be
combined with pixel alpha.
The pixel values in the framebuffers are expected to not be
pre-multiplied by the global alpha associated to the plane.
