Feature/add top clipping

[phobos2390]

Added shortcut that increments and decrements the clip height. Anything above the max clip height is not rendered and ignored for collision detection.

Additional features in this vein could include clip height presets and also ghost placement at the clip height itself.

Sounds like a nice feature. Could you add a video of this in action?

Rather than just making this a shortcut-only function, I think we should add a GUI for this. This could be a fairly simple window. Here's a screenshot of what the equivalent window looks like in OpenRCT2, and how to access it:

Would you like to work on this? Let us know if you need any help.

Since this is basically the OpenRCT2 implementation that was the inspiration I think that'd be the goal. I'm not certain if I can be the developer to implement that view at this time however

[AaronVanGeffen]

Understandable. Would you like me to take over to implement the window, then?

[phobos2390]

Yes

I've rebased the PR on top of current master. Will work on adding a GUI/window soon.
