Robert Bragg 32487af55b Adds a CLUTTER_NEARBYINT macro for float rounding
This is a replacement for the nearbyint function which always rounds to
the nearest integer. nearbyint is a C99 function so it might not always
be available but also it seems in glibc it is defined as a function call
so this macro could end up faster anyway. We can't just add 0.5 because
it will break for negative numbers.
