Setting mesh data leads to a noticeable lag

[wrestledBearOnce]

Setting mesh vertices is lagging in comparison to setting transform component values. Or the other way round.
This leads to a strange "wobbly" behavior when moving objects.

Steps to reproduce

• Generate a new scenegraph with two children
• Attach Transform, Material and Mesh to both
• Calulate mouse delta
• Adapt the Transform.Position value for the first child, move the vertices of the mesh for the second child
• Observe behaviour
• One should move "faster" than the other in terms of reaction speed, not travel distance
• Normalize travel distance between Transform and Mesh vertex movement if necessary (model vs. view coordinate space)

Perhaps this behaviour is fixed with: 2259744

Check and verify.
