High priority work

Adds the ability to schedule and perform high priority work. In the
noop renderer, this is exposed using a method `performHighPriWork(fn)`
where the function is executed and all updates in that scope are given
high priority.

To do this, the scheduler keeps track of a default priority level.
A new function `performWithPriority(priority, fn)` changes the default
priority before calling the function, then resets it afterwards.
