1. GLES2 Compression on Blend Shapes Fix …

   When compressed vertex positions are used in a blend shapes mesh, we
   need to make sure we set the w-component of the position vector to 1.0
   
   When octahedral compression is used on normals/tangents, they need to be
   converted to cartesian floats to be used for blend shapes
   
   This conversion also changes the number of components of that vertex
   attribute, which caused issues because previously there was an
   assumption that you had the same number of components in the blend shape
   buffer as you did in the original mesh's buffer (which is not true for
   oct norm/tang)
