0:21(28): warning: uniform block layout qualifiers row_major and column_major
applied to non-matrix types may be rejected by older compilers

/* From the GL_ARB_uniform_buffer_object_spec:
*
* "Uniform block layout qualifiers can be declared at global
* scope, on a single uniform block, or on a single block member.
*
* At global scope, it is an error to use layout qualifiers to
* declare a variable. Instead, at global scope, layout
* qualifiers apply just to the keyword uniform and establish
* default qualification for subsequent blocks:"
