/**
 *
 * Begins the bitmap re-scaling operation.
 *
 * The scaling factor is based on the relative value of the source bitmap
 * size and the explicitly supplied size. The operation is asynchronous.
 * When it is complete, successfully or otherwise, the
 * <code>TRequestStatus</code>& is set, passing the state of the operation.
 *
 * @param     "TRequestStatus* aRequestStatus"
 *
 * @param     "CFbsBitmap& aBitmap"
 *            The bitmap to be re-scaled. This reference is also the
 *            target location for the re-scaled bitmap.
 * @param     "const TSize& aDestinationSize"
 *            The requested target size for the re-scaled bitmap.
 * @param     "TBool aMaintainAspectRatio = ETrue"
 *            <code>ETrue</code> - the aspect ratio is retained;
 *            this is the default. The same scaling factor is
 *            applied in both the horizontal and vertical
 *            directions. This is the smaller of the horizontal
 *            scaling factor and the vertical scaling factor.
 *            <code>EFalse</code> - the aspect ratio need not be
 *            retained.
