<!-- Actions must be ordered left-to-right even in RTL layout. However, they appear in a chain
with the album art and the title, and must as a group appear at the end of that chain. This is
accomplished by having the guidebox (an invisible view that is positioned around all 5 actions)
in the chain with the album art and the title. The actions are in a LTR chain bounded by that
guidebox, and the ambiguity of how wide the guidebox should be is resolved by using a barrier
which forces it's starting edge to be as far to the end as possible while fitting the actions.
-->
accomplished by having all actions appear in a LTR chain within the parent, and then biasing it
to the right side, then this barrier is used to bound the text views. -->
