Change mj_ray behaviour to match geom visualisation conventions:
...
- Planes and height-fields respect `mj_ray`'s `geom_group` argument.
- The `flg_static` argument now applies to all static geoms, not only those directly in the world body.
Before this change:
- Rays always intersected with height fields and planes, unless `flg_static` was set to 0.
- `flg_static` only applied to static geoms that were direct children of the world, but not geoms that were children of static bodies.
