Fill white space in genre previews
In the Genre view Lollypop generates preview images showing four album cover art images. When there are less than 4 albums to generate the image from the remaining space is white. This does not look so polished compared to all the other nice things in Lollypop.
- For one empty quadrant duplicate the image from the first quadrant to fill up the empty space.
- For two empty quadrants pick the first two images and reverse the order to fill up the empty space.
- For three quadrants fill all the remaining empty space with just this one album art.
I think Google Play Music does this or did this and it looks fine to me.
