Entity::setRescaleNormals

[psquare]

In cases where you know the scale is uniform, it would be good to use GL_RESCALE_NORMAL, rather than GL_NORMALIZE.

Not a DX guy but is this function missing in 'Entity' because there is no equivalent functionality in DX (might be wrong there though)

Entity::setNormaliseNormals is all we can provide here. I highly doubt the difference is great anyway.
