-- | Determine if a unsigned 32-bit value has exactly one bit set.
--
--     If there are no bits set (@x@ is zero), or more than one bit set, this returns false. If any one bit is exclusively set, this returns true.
--
--     Note that this is a forced-inline function in a header, and not a public API function available in the SDL library (which is to say, the code is embedded in the calling program and the linker and dynamic loader will not be able to find this function inside SDL itself).
--
--     [Returns]: true if exactly one bit is set in @x@, false otherwise.
--
--     [Thread safety]: It is safe to call this function from any thread.
