Draft: Raycasting for selectability of foreground objects only

[farfalk]

This is meant as an enhancement of #2028, as it's mostly useful for batch selection of vertices and faces; but because that is a fix and this is a feature proposal, here we are.

If the wireframe mode is enabled, everything becomes selectable.

Check the video below (notice that #2028 is also in use)

This is a Draft because:

1. slows down A LOT with some meshes
2. in some cases it fails to select foreground faces

Check video below for an example of both problems

@JannisX11 have you got any suggestion?

[farfalk]

Both issues are solved with the latest commit.
I still think performance could be improved a bit more, but there's already no comparison with the previous version. On my machine, selection with lots of objects takes away about 5-10 fps max

@JannisX11 is this interesting to you? If so, do you have any hint about how to proceed in terms of performance?

Thanks stalebot, forgot about this. @JannisX11 is this still worth looking into?
