Size the now-playing info block to its content, spectrum fills the rest 

Instead of a fixed info-block height, derive it from the number of info
lines (4 with a track, 3 without) plus the border, and let the spectrum
take all remaining rows. Both regions now size themselves: the info
block is exactly as tall as it needs, the bars fill everything left.
