Improve the Resolution of Music Artwork in the UI

[lakerssuperman]

PR #884 fixes pixellated artwork on the Now Playing screen and album artwork screensaver. Matching the artwork clarity in other areas would be great for consistency and polish.

Areas to consider:

1. The album detail page. (see screenshot). This is not as sharp as Now Playing with PR 884 and looks like it should be.
   

2. The music collection album grid view. This is pretty sharp as is and may not be able to be improved, but worth checking.

3. The Latest Music section of the home scree. As with the album view, it is very sharp already, but checking if it is at best resolution can't hurt.

#2 and #3 may also be limited by the size of the icons used in these areas and the scaling. They may not be able to be improved.
