# Description

Previously, the method for randomizing masses of rigid bodies only set
the masses. However, the inertia tensors were not automatically updated,
and their original values were used inside the solver. This MR adds a
flag to recompute the inertia when mass is randomized by assuming a
uniform-density object. We make this an optional flag in case users want
to handle inertia tensors explicitly on their own.
