# Minor optimisations and features.

Made CMatrix3D::Translate assume something sensible about the structure
of the matrix, so it doesn't have to do a matrix multiplication.
Added quaternion nlerp (but haven't used it anywhere).
Changed animation interpolation so it loops smoothly in the actor viewer
but (hopefully) doesn't interpolate dying units into a half-upright
pose.

This was SVN commit r4932.
