/** 
Encapsulates the information required for one frame of an animation. 

Each animation frame includes a bitmap that is displayed in a specified position 
for a specified length of time. You can optionally include a mask that either 
hides part of the bitmap, or makes part of the bitmap transparent so that the 
background can be seen.

You will probably need to define several frames for a complete animation. 
When you have defined the frames you require, use CBitmapAnimClientData to 
construct the animation itself.

/** 
Encapsulates one or more animation frames into an entire animation.

In addition to specifying the frames you wish to include in your animation, 
you can also specify:

- whether the animation will flash

- whether the animation is played once, or continuously

- the background frame that is drawn to clear each frame in the animation

You can also specify a default frame interval that is used for all frames 
in an animation. If the interval is already set for any of the individual 
frames, that takes precedence.

When you have defined your animation, use RBitmapAnim to play the animation.
