annotate src/video/dummy/SDL_nullrender.c @ 2247:93994f65c74c

Removed hermes since it's LGPL and not compatible with a commercial license. Prepping for using MMX and SSE intrinsics instead of inline assembly. .. except for memcpy equivalents which only get faster if they can exploit the parallelism of loading into multiple SIMD registers. :)
