 * Section 5.10 (Constant Expressions) of the GLSL ES 1.00.17 spec says:
 *
 *     "A constant expression is one of

 *         ...
 *
 *         - a built-in function call whose arguments are all constant
 *           expressions, with the exception of the texture lookup functions."

 * While the sequence operator is specifically disallowed as a constant
 * expression in GLSL ES 3.0 and later, it is allowed in GLSL ES 1.00.
