Yeah, I spotted that.  But I think it may be a mistake (or at the very
least a spec inconsistency), for the following reason: chapter 11 of the
GLSL ES 3.00 spec ("Counting of Inputs and Outputs") specifies the order in
which varyings should be packed according to their type, and it does not
specify what to do about varyings of type struct.  This chapter would have
to be extended in a non-trivial way to be consistent with GLSL ES 3.00
allowing varying structs.  Also, there are no GLES3 conformance tests that
require varying structs.

Considering this inconsistency, as well as the fact that no conformant
implementations of GLES3 have yet been released, I wonder if it would be
worth trying to lobby the Khronos board to have this part of the spec
changed.
