101 * - It can only be used with one-variant-per-shader support, in which
102 * case only the main (typically middle) part of shaders is cached.
103 * - Only VS, TCS, TES, PS are cached, out of which only the hw VS
104 * variants of VS and TES are cached, so LS and ES aren't.
105 * - GS and CS aren't cached, but it's certainly possible to cache
