-Three.js also sorts morphtargets and applies only the highest influences.
-This lets it allow many more morphtargets as long as only a few are used at

-morph targets will be used nor which attributes the morph targets will be
-assigned. So, we'll have to look into the code and reproduce what it does

-First removing all our color attributes. It doesn't matter if we added them
-before as it's safe to remove an attribute that was not previously added.
-Then we'll compute which targets we think three.js will use and finally
-assign those targets to the attribute we think three.js would assign them.
