    \class MpAlbumCoverWidget
    \brief Album Cover Widget.
    This widget provides up scaled rendering of images and SVG rendering.

    This widget can be used instead of HbLabel or HbIconItem when up scaling 
    and downscaling during painting is desired, there is no need to preprocess
    images to the target size, this is taken care of during paint in a more 
    efficient manor; this widget renders images flush with the geometry.
    Default icon placeholder is also supported.
