24 * The ivi-layout library supports API set of controlling properties of
25 * surface and layer which groups surfaces. An unique ID whose type is integer
26 * is required to create surface and layer. With the unique ID, surface and
27 * layer are identified to control them. The API set consists of APIs to control
28 * properties of surface and layers about followings,
31 * - clipping (x,y,width,height).
32 * - position and size of it to be displayed.
33 * - orientation per 90 degree.
34 * - add or remove surfaces to a layer.
35 * - order of surfaces/layers in layer/screen to be displayed.
36 * - commit to apply property changes.
37 * - notifications of property change.
39 * Management of surfaces and layers grouping these surfaces are common way in
40 * In-Vehicle Infotainment system, which integrate several domains in one system.
41 * A layer is allocated to a domain in order to control application surfaces
42 * grouped to the layer all together.
