+ * ES). This is stored as \c gl_constants::MaxVarying.
+ *
+ * Starting with OpenGL 3.2, the limits are advertised with per-stage
+ * variables. Each stage as a certain number of outputs that it can feed
+ * to the next stage and a certain number inputs that it can consume from
+ * the previous stage.
+ *
+ * Vertex shader inputs do not participate this in this accounting.
+ * These are tracked exclusively by \c gl_program_constants::MaxAttribs.
+ *
+ * Fragment shader outputs do not participate this in this accounting.
+ * These are tracked exclusively by \c gl_constants::MaxDrawBuffers.
