/**
* Implementation of ivi-layout library. The actual view on ivi_screen is
* not updated till calling ivi_layout_commit_changes. A overview from
* calling API for updating properties of ivi_surface/ivi_layer to asking
* compositor to compose them by using weston_compositor_schedule_repaint,
* 0/ initialize this library by ivi_layout_init_with_compositor
* with (struct weston_compositor *ec) from ivi-shell.
* 1/ When a API for updating properties of ivi_surface/ivi_layer, it updates
* pending prop of ivi_surface/ivi_layer/ivi_screen which are structure to
* store properties.
* 2/ Before calling commitChanges, in case of calling a API to get a property,
* return current property, not pending property.
* 3/ At the timing of calling ivi_layout_commitChanges, pending properties
* are applied to properties.
*
* *) ivi_layout_commitChanges is also called by transition animation
* per each frame. See ivi-layout-transition.c in details. Transition
* animation interpolates frames between previous properties of ivi_surface
* and new ones.
* For example, when a property of ivi_surface is changed from invisibility
* to visibility, it behaves like fade-in. When ivi_layout_commitChange is
* called during transition animation, it cancels the transition and
* re-start transition to new properties from current properties of final
* frame just before the the cancellation.
*
* 4/ According properties, set transformation by using weston_matrix and
* weston_view per ivi_surfaces and ivi_layers in while loop.
* 5/ Set damage and trigger transform by using weston_view_geometry_dirty.
* 6/ Notify update of properties.
* 7/ Trigger composition by weston_compositor_schedule_repaint.
