				SeverinUnsubmitted Not Done Inline Actions Fails to compile here on Apple Clang, because of undefined type `uint`. I had to include "BLI_sys_types.h". Why is this using unsigned anyway? There are probably plenty of hidden bugs in Blender because of unsigned-signed comparisons, and I know Sergey is quite against using them too.

				JacquesLuckeAuthorUnsubmitted Done Inline Actions I made it unsigned, because I was too lazy to find a version that works correctly for negative and positive numbers. Also, I don't a case where this behavior would be useful for negative values. JacquesLucke: I made it unsigned, because I was too lazy to find a version that works correctly for negative…
