+# Section 4.3.8.1 (Input Layout Qualifiers) of the GLSL 1.50 spec says:
+#
+# At least one geometry shader (compilation unit) in a program must
+# declare an input layout, and all geometry shader input layout
+# declarations in a program must declare the same layout. It is not
+# required that all geometry shaders in a program declare an input
+# layout.
+#
+# This test verifies that a link error occurs if no compilation unit
+# declares an input layout.
