Adding protections for invalid flex parameters

[arthmis]

Ok, not sure if there are better ways to clamp a value above a certain threshold. Also, is it fine to do the tests like that? I had to do it that way otherwise the test fails in release and passes debug.

Thanks! A couple notes inline :)

I opted to keep add_child within with_child instead of relying on the add_flex_child function checking for flex values that are 0.0 or less.

Looks good! A few little formatting nits, but happy to see this merged. :)

What's the conclusion here?

[arthmis]

In regards to what? Are there any other issues? The only one that came up was the tracing events need a subscriber created before the app is launched but that is a separate issue.

oh oops, I'm going to take out the tracing instrument for the add flex child function. I forgot. Other than that I think everything is fine.
