 * Section 4.3 (Storage Qualifiers) of the OpenGL ES 3.00.4 spec says:
 *
 *     "Initializers may only be used in declarations of globals with no
 *     storage qualifier or with a const qualifier.  Such initializers must be
 *     a constant expression."
 *
 * This differs from desktop GLSL.  A compiler that only has to support GLSL
 * ES could possibly be some amount smaller due to this restriction.
 *
 * Section 4.3.3 "Constant Expressions" of the OpenGL GLSL ES 3.00.4 spec
 * says:
 *
 *     "However, the sequence operator ( , ) and the assignment operators ( =,
 *     +=, ...)  are not included in the operators that can create a constant
 *     expression."
