 Hosts may build multiple graphs with different master clocks.

Shouldnt this be "at least one", theres no reason why the host might not present two different timelines to two different plugins in the same graph - if it wanted to. Isnt the intention that a give plugin should only be presented with one distinct timeline?

the master clock is *not* the same as a timeline. plugin's can be presented with different timelines, but there is only one master clock.

Speaking of multiple time coordinates that could conflict, can someone remind me again why an event needs both sample clock and UST? What does the plug do when they don't agree, pick whichever one it like better?
