Features Currently Worked On (most likely to be implemented next):
- 'Altitude lines' - lines drawn from the grid to the ship to make its 3D position more obvious (almost done, just need to make sure they always update).
- Vector triangle - a triangular 3D helper for visualizing vector position and 3D angle relative to ship (not visible in 2D mode due to having zero height).
- Target lines (actually trivial/almost done, but require the targeting interface to be of use outside a dev/debug assembly).
- Alternate square grid for Rogue Trader.
