-/**
- * Program key structures.
- *
- * When drawing, we look for the currently bound shaders in the program
- * cache. This is essentially a hash table lookup, and these are the keys.
- *
- * 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.
