The only difference I found is that it is not possible to change the
binding point associated with a shader storage block after a program is
linked (see section 7.8 "Shader Buffer Variables and Shader Storage
Blocks"). Because of that, glShaderStorageBlockBinding() is not defined
for GLES 3.1.

I will write a follow-up patch to enable this extension for GLES 3.1 and
another one to update the docs.

Thanks,

Sam
