+# From the GLSL 1.50 specification, section 4.3.4 ("Inputs"):
+#
+# "For the interface between a vertex shader and a geometry shader, vertex
+#  shader output variables and geometry shader input variables of the same name
+#  must match in type and qualification, except that the vertex shader name
+#  cannot be declared as an array while the geometry shader name must be
+#  declared as an array. Otherwise, a link error will occur."
