[Feature]: VBL/MBL adjustable displayed line width

[icarean]

Feature Request

Please could we have a setting to adjust the displayed VBL and MBL line widths?

The Solution you'd like

I find VBL and MBL lines difficult to see, and I'd like to be able to make them more obvious. However I understand changing the thickness of VBL and MBL lines would have potential to affect vision and movement (i.e. I'm guessing as currently implemented a thicker line would block more of the map). So my suggestion is both of the following be implemented together:

1. VBL and MBL lines be infinitesimally thin (implemented as math/theoretical lines between two defined points, etc)
2. A setting be added to the Edit -> Preferences -> Application tab for "VBL/MBL display width" (as per "Halo line width" under "Map Visuals"). This setting should be a number of pixels or another relevant scaled measure, and only affect how the GM sees the VBL/MBL lines displayed on their map but in no way affect how vision and motion interact with the infinitesimally thin actual lines specified in Can't yet build a distribution. #1 above. This setting would not affect filled areas (I acknowledge there's an edge case where someone draws a very thin area).

Alternatives that you've considered.

Continuing to squint at the screen and 'zoom in' by leaning closer :)

In a non-obvious way, this is related to #3485. Both FRs touch on the fact that each *BL type as one area (literally a java.awt.Area) which prevents us from having multiple areas (which is that FR) or ideal lines (which is this request). Both require a change of our internal representation.

IMO we treat this as an opportunity to pick a new representation that is easily consumable by our vision and pathfinding algorithms, and that will be flexible enough to support improvements (such as ideal lines, editability, overlap, improved visualization, etc). I expect there would also be some performance improvements if we ditched Area for *BL in favour of something more direct.
