Hi Drake,
You could have a matrix wrapped up in your custom GizmoDrawable but you'd
have to be careful about when you passed on the matrix.
One normally doesn't cache matrices this way, as it usually isn't
required. There is chance that you are trying to tackle a problem that
there is an established and better solution, but as don't say anything
about the actual problem you trying to solve, just focus on possible
solution to an unknown problem we can't provide any useful advice.
