We were assuming 32-bit elements. Also, In SIMD8 we pack 2 vector components in a single SIMD register, so for example, component Y of a 16-bit vec2 starts is at byte offset 16B. This means that when we compute the offset of the elements to be differentiated we should not stomp whatever base offset we have, but instead add to it. v2 - Use byte_offset() helper (Jason) - Merge the fix for SIMD8: using byte_offset() fixes that too.
