Investigate issues generating large solo nav meshes

Above is an example output when attempting to generate a solo nav mesh for a larger mesh.

The heightfield is successfully generated for the whole mesh (visualised in blue and green in the second screenshot) but something else is going wrong in the nav mesh generation process.

This just be an issue with the debug nav mesh representation, at least partially.

In the above example, the agent is able to traverse an area of the nav mesh that the debug nav mesh hasn't captured.
