    1.39 +/**
    1.40 +Implementation of CAnimation for purely client side animations.
    1.41 +
    1.42 +A basic animation accepts a data provider during construction, loads the
    1.43 +appropriate animator plugin, and implements the interface defined in
    1.44 +CAnimation.
    1.45 +
    1.46 +A basic animation must be associated with an RWindow.  Redraw events will be
    1.47 +received by the client application whenever the animation needs to draw a new
    1.48 +frame, and it is the applications responsibility to call Draw() while handling
    1.49 +these events.  It is also the client applications responsibility to handle
    1.50 +visibility events and place the animation on hold when it isn't visible. This
    1.51 +saves on CPU usage and ultimately prolongs battery life.
