Bonsai: Element visibility options

issue: https://github.com/IfcOpenShell/IfcOpenShell/issues/6425

Hi,

The fourth item in the Drawings & Documentation proposal: https://community.osarch.org/discussion/2640/drawings-documentation-donation-proposal#latest

This is closely related to the second item #6423

Option to choose element visibility, like slab a should have automatic dashed countours only, but slab b should look different like a filled grey area.

These visibility options should all relate and make use of the predefined line types etc.

Much appreciated!

General Note about Projects: 

Anyone familiar with software development knows that it's sometimes hard to determine when exactly the project is complete.   Even when the scope is clearly defined, quite often there's a sense that more can be done to refine the project.  This is unavoidable, so in that light, to be fair to both the funders and solution providers, the steering committee will act as the arbiter to determine when the project is done and when the funds should be distributed.  When it's 'done' will also be a factor of how much the funding is relative to how involved the scope is.  That is say, if a very small amount of funding is provided, for a solution that would require a lot more funding, the steering committee can allocate funds for partial solutions, as well.

Please note, if no one provides a solution to the project with a year (365days), the funds dedicated to this project will be transferred over to OSarch's general funding. The OSArch steering committee will then allocate the funding to other projects.
