Ok, fair enough. /me shakes fist at the list of "removed from 3.30" GLSL
spec section not mentioning it.


Chalk it up to another trivial divergence of ES in unexpected way.

Probably not worth it then. Everyone will have to support "no initializers"
case for the foreseeable future if that's what all current implementations
do.

Thanks for the info!
