+ *
+ * Sometimes OpenGL features specified as state need to be simulated via
+ * shader code, due to a mismatch between the API and the hardware.  This
+ * is often referred to as "non-orthagonal state" or "NOS".  We store NOS
+ * in the program key so it's considered when searching for a program.  If
+ * we haven't seen a particular combination before, we have to recompile a
+ * new specialized version.
+ *
+ * Shader compilation should not look up state in gl_context directly, but
+ * instead use the copy in the program key.  This guarantees recompiles will
+ * happen correctly.
