Improve realtime performance with better filtering. about presentmon HOT 4 CLOSED

Hey Jesse, just fyi I have this implemented and will push once tested/scanned.

It doesn't seem to work when consuming ETL, but I only get used events when capturing realtime. I measured capturing a simple graphics app for 30s and observed 0.6x cpu time.

That's awesome! Yeah, it's only a property that applies to the producing side, not the consuming side. You should also see reduced CPU overhead from the components producing the ETW, because they should be sending less data.

Thanks for tackling this!

Pushed to master. I also made a change where I always use the event metadata and populate it if it's missing, which also has a significant performance benefit.

I'll leave it in master for a bit to give time to shake out any issues, then will create a new versioned release.

Wow, I'm really impressed by the amount of refactoring and improving that just happened. Great job!
