Misc Fixes

[coolbutuseless]

Feature

• [ ] Change coordinate system to xyplane = 'flat' with z vertical (RH coordinate system)
• [ ] Add drawing of ground to help set perspective.
  • [x] with gridlines
  • [x] with just points
  • [ ] Fix unit handling for size in isolinesGrob() and isopointsGrob() i.e. if size has a unit, then respect that.
  • [ ] Tweak alignment (grid lines -vs- cubes) and grid line thickness to make this look better.
  • [ ] Add example of gpar() arguments for both lines and points. e.g. lty, lwd, pch etc
• [ ] export: find_visible_voxels(coords, xyplane, handedness)
• [ ] Remove default.units argument. (x,y) positioning will always be assumed to be npc units unless already unitized.
• [ ] Rename default.units.cube to be default.units (and set to mm)
• [ ] Revisit terrain rendering. More flexibility in arguments / orientation.
• [ ] Simple rotate/translate tools for coords data.frames (see rgl and csg)
• [x] Add isoaxesGrob()
  • [x] adjust coordinates so that (0, 0, 0) cube is always correctly positioned w.r.t. the axes
