Mike Reed 9e62df6ecd Revert "store vertices arrays inline with object"
This reverts commit eaaebb19a1.

Reason for revert: may call SkReader32::read(null, 0) -- reader needs to handle this

Original change's description:
> store vertices arrays inline with object
> 
> Also unify some of naming (esp. around texCoords)
>
