+# Section 2.11.2 (Program Objects) of the GLSL 1.50 spec says:
+#
+# "Linking will also fail if the program object contains objects to form a
+#  geometry shader (see section 2.12), and
+#	• the program contains no objects to form a vertex shader;
+#	• the input primitive type, output primitive type, or maximum output
+#	  vertex count is not specified in any compiled geometry shader object;
+#	• the input primitive type, output primitive type, or maximum output
+#	  vertex count is specified differently in multiple geometry shader
+#	  objects."
