  indention fixed
  second one must be yv12touyvy instead of yv12toyuy2
  replace slow modulo by bitwise and
  move %16!=0 code before the comment saying the code cant handle %16!=0

- Fixed PlanarToNV12Wrapper() and made it handle NV21.
- Added yuv2nv12XinC() to handle software scaling.
- Added NV12/NV21 handling to various places.
- Removed NV12 from vf_hue and vf_spp as they don't look like they can
  actually handle it.
