annotate src/cpuinfo/SDL_cpuinfo.c @ 3495:1b22878e04d0

Adam Strzelecki to SDL D3D renderer shall try mapping YV12 and I420 (IYUV) to D3D texture formats via FOURCC. This will enable HW acceleration for those formats when driver is capable (most of them are). Note that SDL's IYUV maps I420 FOURCC on Woe.
