 When possible, MuJoCo exploits sparsity. This can make all the difference between O(N) and O(N^3) scaling. The inertia
 matrix ``mjData.qM`` and its LTDL factorization ``mjData.qLD`` are always represented as sparse. ``qM`` uses a custom
 indexing format designed for matrices that correspond to tree topology, while ``qLD`` uses the standard CSR format.
