Animations are run off the repaint cycle so if there's nothing to repaint, an animation will stop running. This is usually not a problem as each frame function of an animation causes something to change and therefore a repaint to happen. This patch helps detect when the animation isn't in said case and triggers a repaint to keep the animation running. This problem was found by using weston_move_scale_run() to move a view onscreen from completely off. The very first time the animation frame function was called the progress wasn't enough to move it into view. The compositor saw there was nothing to repaint and stopped doing anything else. When something else (like a pointer move) forced a redraw, the view's position was very much onscreen and jumped into view in an ugly way.
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for building weston and its dependencies. The test suite can be invoked via `make check`; see http://wayland.freedesktop.org/testing.html for additional details.
