Change Preselect and L>R Cross Select Behavior

[Ryan_Williams-MRB]

For preselection and left to right cross selection, ignore hidden geometry, ignore reference planes extending past visible geometry to the extents of hidden geometry, (maybe) ignore subfamilies. The user just wants to interact with what they see! For example, I have a clear floor space family that has side reach range parameters that can be toggled on. Even if those reach ranges are off, the extents of the family still recognize where the hidden reach ranges are when trying to select. You get nuisance pre-selection when trying to pick other objects, and you can't left to right cross select tightly around the visible portion of the object.

Oh yes...

We have families with influence circunferences of 25m like firehose reels and taps, etc, that are a pain to work because of that.

We end up selecting them without realising it when using window selection and even the family preview in the property window gets so small it's invisible because it uses that line as object extents. It doesn't mather if its a 3D or 2D line and it doesn't mather if it's visible or invisible by default...

The family editor should ignore 2D lines from the family preview and only select a family in the project if actual geometry or lines are crossed (not empty space in between or invisible lines/geometry, just like this idea says).
