Trait for finding Points in Frustum

[ksavinash9]

Currently, implementation of Frustum has method for finding the spatial relation of a bound inside this frustum, but not for finding the points.

Is this intentional?

Probably just an oversight, this was created before I joined the project.

@Rhuagh Shall I send a PR for that?

Absolutely, if you have time to do so, we love PRs :)
