+    \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.
