gui_toolkit 0.111.2

Fixed

• Wayland: a wait sleeps through the renderer's own traffic: the presentation feedback and the FIFO events of the frame just shown, and the ids of the renderer's callbacks, made the connection readable at each refresh, and every wait ended there: a window at rest drew a frame at each refresh. A wait now ends on what is the window's (its input, a repaint asked for), a change of the clipboard, a wake, a bus or the time. tests/linux_desktop checks that a wait at rest sleeps its time.
