Attempt to speed up outside bed detection (#8869)

Browse Source 
* Don't check intersection if points below bed is also inside the bed, when the bed is convex

* Skip intersection check if bbox not overlapping

* Remove duplicated out of bed check

* Faster (but less accurate) bbox test

* Merge branch 'main' into dev/faster-outside-check
