Comments

This function starts an animation playback. In order to play an animation, you must call LAnimationWindow::Load or LAnimationWindow::SetBitmapList prior to calling this function. You can also pass an LBitmapList object using the constructor.

If the animation is already started, the function will return WRPERR_ANIMATION_ALREADY_STARTED.

If the loaded file is not a valid file, the return value will be WRPERR_ANIMATION_INVALID_FILE.
