Sergey Sharybin 4d38932cb4 Cycles: Use more stable version of integer square root function ... Old code was working quite unreliable in combination with fast math flag, especially when compiling with Clang. It seems we were hitting result of the following bug submitted to Clang [1]. Basically, it was happening so that (int)sqrtf(64) was 7 when Cycles is built with Clang but was correct 8 when built with GCC. This commit works this around. Annoying, but don't see other way to keep sampling pattern the same for Clang and GCC. [1] https://bugs.llvm.org//show_bug.cgi?id=24063		2017-05-09 17:07:17 +02:00
