/** ScaleProcess: Class to rescale the whole model.
* Now rescales animations, bones, and blend shapes properly.
* Please note this will not write to 'scale' transform it will rewrite mesh
* and matrixes so that your scale values
* from your model package are preserved, so this is completely intentional
* bugs should be reported as soon as they are found.
