function RotatePointCloud(rotmat::AbstractArray{<:Number,2}; inplace::Bool = true)

right now implements rotation such that N PointClouds or N TriMeshes (N --> batch dim) are rotated by the same matrix. I feel an important addition would be to extend to work with N rotation matrices.

This is particularly useful in rendering applications where you need different projections for meshes which don't follow the same alignment
