Motion Blur and InstancedMesh

[Peters69]

Description

Motion Blur is a nice post-production effect. However, using instanced meshes, it appears that something is not working correctly. As soon as a matrix changes the position of an instance, it shows render issues.

It seems InstanceNode needs a similar enhancement like SkinningNode in order to compute positionPrevious correctly. Meaning if there is a velocity MRT output, InstanceNode must keep track of the previous instance matrices (previousInstanceMatrixNode)
