      Description

      Launch submitted app.

      It is a simple usage of Canvas for animation.

      In Windows 7 ( don't know about other OS's ) when you press Ctrl+Alt+Delete ( to launch Task Manager, for example ) it totally freezes.

      While app not exits by exception, animation stopped, CPU used hardly and memory quickly wasted ( from 30 MB up to 1000 MB and more )

      CPU usage and speed of memory consumption depend of how many graphicsContext.doSomething() operations used.

      Meanwhile, app still runs and System.out.println() really outputs data.
