6 * From page 20 (page 26 of the PDF) of the GLSL 1.20 spec:
8 * "In some situations, an expression and its type will be implicitly
9 * converted to a different type. The following table shows all allowed
10 * implicit conversions:
12 * Type of expression Can be implicitly converted to
18 * There are no implicit array or structure conversions. For example, an
19 * array of int cannot be implicitly converted to an array of float. When
20 * an implicit conversion is done, it is not just a re-interpretation of
21 * the expression's value, but a conversion of that value to an equivalent
22 * value in the new type. For example, the integer value 5 will be
23 * converted to the floating-point value 5.0. The conversions in the
24 * table above are done only as indicated by other sections of this

35 gl_Position = vec4(b[0], b[0], b[1], b[1]);
