+* Section 4.3.8.1 (Input Layout Qualifiers) of the GLSL 1.50 spec says:
+*  Fragment shaders can have an input layout only for redeclaring the
+*  built-in variable gl_FragCoord (see section 7.2 Fragment Shader Special
+*  Variables). The layout qualifier identifiers for gl_FragCoord are
+*      layout-qualifier-id:
+*          origin_upper_left
+*          pixel_center_integer
+* This test is just a check to make sure the arb_fragment_coord_conventions
+* extension is switched on in core compiler.
