Pekka Paalanen edcb312abb ivi-layout: clarify get_layers_under_surface doc
This is derived from the implementation. I was not sure whether "under"
referred to object relationships or region intersections.

/**
* The ivi-layout library supports API set of controlling properties of
* surface and layer which groups surfaces. An unique ID whose type is integer
* is required to create surface and layer. With the unique ID, surface and
* layer are identified to control them. The API set consists of APIs to control
* properties of surface and layers about followings,
* - visibility.
* - opacity.
* - clipping (x,y,width,height).
* - position and size of it to be displayed.
* - orientation per 90 degree.
* - add or remove surfaces to a layer.
* - order of surfaces/layers in layer/screen to be displayed.
* - commit to apply property changes.
* - notifications of property change.
*
* Management of surfaces and layers grouping these surfaces are common
* way in In-Vehicle Infotainment system, which integrate several domains
* in one system. A layer is allocated to a domain in order to control
* application surfaces grouped to the layer all together.
*
* This API and ABI follow following specifications.
