/*
 * Basic screenshot test for output decorations
 *
 * Tests that the cairo-util code for drawing window decorations works at all
 * through headless-backend. The window decorations are normally used as output
 * decorations by wayland-backend when the outputs are windows in a parent
 * compositor.
 *
 * This works only with GL-renderer. Pixman-renderer has no code for blitting
 * output decorations and does not even know they exist.
 *
 * Headless-backend sets window title string to NULL because it might be
 * difficult to ensure text rendering is pixel-precise between different
 * systems.
