For the rest, we defer to the rIC period and work down each queue from high to low.

Strategy:
|
||||
- When called, check for any UI events that might've been received since the last frame.
|
||||
- Dump all UI events into a "pending discrete" queue and a "pending continuous" queue.
|
||||
|
||||
- If there are any pending discrete events, then elevate our priority level. If our priority level is already "high,"
|
||||
then we need to finish the high priority work first. If the current work is "low" then analyze what scopes
|
||||
will be invalidated by this new work. If this interferes with any in-flight medium or low work, then we need
|
||||
to bump the other work out of the way, or choose to process it so we don't have any conflicts.
|
||||
'static components have a leg up here since their work can be re-used among multiple scopes.
|
||||
"High priority" is only for blocking! Should only be used on "clicks"
|
||||
|
||||
- If there are no pending discrete events, then check for continuous events. These can be completely batched
|
||||
|
||||
- we batch completely until we run into a discrete event
|
||||
- all continuous events are batched together
|
||||
- so D C C C C C would be two separate events - D and C. IE onclick and onscroll
|
||||
- D C C C C C C D C C C D would be D C D C D in 5 distinct phases.
|
||||
|
||||
- !listener bubbling is not currently implemented properly and will need to be implemented somehow in the future
|
||||
- we need to keep track of element parents to be able to traverse properly
|
||||
|
||||
|
||||
Open questions:
|
||||
- what if we get two clicks from the component during the same slice?
|
||||
- should we batch?
|
||||
- react says no - they are continuous
|
||||
- but if we received both - then we don't need to diff, do we? run as many as we can and then finally diff?
