Huum, the alpha being premultiplied or not seems to be a property of the
framebuffer to me, not of the plane. It seems to me that we should
define alternative premultiplied DRM_FORMATs and make the sprite planes
advertise support for premultiplied fbs in the format list when the
hardware indeed supports them.
