Author: Brian Paul <[email protected]> Date: Wed Aug 17 10:41:30 2016 -0600 util: try to use SSE instructions with MSVC and 32-bit gcc The lrint() and lrintf() functions are pretty slow and make some texture transfers very inefficient. This patch makes a better effort at using those intrisics for 32-bit gcc and MSVC. Note, this patch doesn't address the use of SSE4.1 with MSVC. v2: get rid of the ROUND_WITH_SSE symbol, per Matt.
