Functions
fl::i32	fl::gfx::detail::isqrt32_ceil (fl::i32 n)
	Integer square root using Newton iteration Computes ceil(sqrt(n)) for positive integers More accurate than digit-by-digit for the ceiling case.
fl::i32	fl::gfx::detail::isqrt32_floor (fl::i32 n)
	Integer square root using digit-by-digit algorithm Computes floor(sqrt(n)) for positive integers Uses only shifts, adds, and comparisons — no division.
